See what your bloodwork may reveal.

The protein that binds testosterone in circulation and regulates how much is biologically available. High SHBG can mean total testosterone reads normal while free testosterone runs low.

The primary form of estrogen in circulation, present in both men and women. In men it reflects how much testosterone is being converted to estrogen; in women it tracks ovarian function across the cycle and into menopause.

A reproductive hormone that rises in the second half of the menstrual cycle and is required for cycle regularity and early pregnancy. Levels also reflect ovulation status and luteal-phase function.

A pituitary hormone that signals the gonads to produce sex hormones. In men it reflects the brain's drive on testicular function; in women it triggers ovulation and tracks reproductive-stage shifts.

The other pituitary signal to the gonads, paired with LH on most reproductive panels. Levels indicate egg-reserve status in women and testicular function in men.

A pituitary hormone elevated by stress, certain medications, and prolactinomas. High prolactin can suppress testosterone in men and disrupt cycles in women, so it sits on every reproductive panel.

An adrenal hormone that serves as a precursor to both testosterone and estrogen. Levels reflect overall adrenal output and tend to decline steadily with age.

An adrenal and gonadal precursor that converts into both testosterone and estrogen. Particularly informative on women's panels where it tracks PCOS-pattern androgen excess.

A marker of ovarian reserve, reflecting the size of the resting follicle pool. AMH levels are relatively stable across the menstrual cycle, which makes it a useful complement to FSH and estradiol on a reproductive panel, particularly in the context of fertility evaluation.

Measures the level of glucose in your blood after an overnight fast. The standard screen for diabetes and prediabetes, though it tends to move late in the progression of insulin resistance.

Measures the amount of insulin your pancreas is producing at rest. Fasting insulin can rise well before fasting glucose moves out of range, so it is associated with early shifts in insulin sensitivity that a glucose-only screen would miss.

Reflects average blood-sugar levels over the prior three months by measuring the percentage of hemoglobin that has bound glucose. A more stable read than a single fasting glucose draw.

A calculation derived from fasting glucose and fasting insulin that estimates the degree of insulin resistance at rest. HOMA-IR can shift before fasting glucose alone moves out of range and is read alongside the other metabolic markers on the panel rather than on its own.

The combined level of all cholesterol fractions in your blood. A starting read on cardiovascular profile, though the breakdown into LDL, HDL, and triglycerides carries more interpretive weight than the total alone.

Low-density lipoprotein cholesterol — the fraction associated with plaque buildup in artery walls. The standard read on atherogenic cholesterol, paired with ApoB on a comprehensive panel for greater specificity.

High-density lipoprotein cholesterol — the fraction that transports cholesterol back to the liver for clearance. Higher levels are associated with lower cardiovascular risk.

A type of fat in the blood that rises with carbohydrate intake, alcohol, and insulin resistance. Elevated triglycerides are associated with metabolic dysfunction and cardiovascular risk.

The full lipid set drawn from a single sample — total cholesterol, LDL, HDL, and triglycerides — reported together with the calculated ratios labs derive from them.

Measures the count of plaque-forming particles in your blood directly, rather than the cholesterol cargo they carry. ApoB is considered one of the more specific markers of atherogenic cardiovascular risk and is increasingly recommended in addition to a standard lipid panel.

A high-sensitivity measure of low-grade systemic inflammation. Persistently elevated hs-CRP is associated with cardiovascular risk independent of cholesterol levels.

An amino acid that accumulates when B-vitamin metabolism is impaired. Elevated levels are associated with vascular inflammation and cardiovascular risk and often track back to low B12 or folate.

A pituitary hormone that signals the thyroid to produce T4 and T3. The standard first-line thyroid screen, though TSH alone can sit inside the reference range while downstream thyroid hormones run out of yours.

The unbound, biologically available form of thyroxine — the main hormone the thyroid produces. Levels indicate how much T4 is actually circulating and available to tissues for conversion to active T3.

The unbound, biologically active form of triiodothyronine — the thyroid hormone that does the work at the cellular level. Often runs low in cases of impaired T4-to-T3 conversion.

An inactive isomer of T3 produced under stress, illness, or caloric restriction. Elevated reverse T3 is associated with situations where T4-to-T3 conversion shifts toward the inactive form, and is read alongside Free T3 and Free T4 on a comprehensive thyroid panel.

Antibodies against thyroid peroxidase, the enzyme involved in thyroid hormone production. Elevated TPO antibodies are associated with autoimmune thyroid conditions, including Hashimoto's thyroiditis, and can be present years before standard thyroid markers shift.

Measures cortisol levels drawn in the early morning, when they should be at their daily peak. The standard read on adrenal output and a baseline for diagnosing high-cortisol or low-cortisol patterns.

The other primary adrenal hormone, often read alongside morning cortisol to map the adrenal output ratio. Tends to decline with age and with sustained HPA-axis activation.

The pituitary hormone that signals the adrenal glands to produce cortisol. Reading ACTH alongside cortisol can indicate whether a cortisol abnormality originates in the adrenal glands or upstream in the pituitary.

The pituitary hormone that supports tissue repair, lean mass, and the deeper stages of sleep. hGH is pulsatile and difficult to interpret from a single draw, so it is typically read alongside IGF-1.

A liver-produced hormone that reflects integrated growth-hormone activity over the prior several days. Considered the more stable read on growth-hormone status and tends to decline gradually from the late twenties forward.

Measures 25-hydroxyvitamin D, the storage form that reflects overall vitamin D status. Low levels are associated with fatigue, mood changes, bone-density loss, and immune dysfunction, and are common in Canadian climates.

A water-soluble vitamin required for red blood cell formation, neurological function, and energy metabolism. Low B12 is associated with fatigue, cognitive symptoms, and a specific pattern of anemia.

A B-vitamin required for DNA synthesis, red blood cell production, and homocysteine metabolism. Often read alongside B12 because the two work together and deficiency in either produces similar symptoms.

A mineral involved in over three hundred enzymatic reactions, including muscle function, nerve signalling, and sleep regulation. Low magnesium is associated with cramps, poor sleep, anxiety symptoms, and elevated blood pressure.

A trace mineral involved in immune function, wound healing, testosterone production, and taste perception. Zinc deficiency is associated with frequent infections, slow healing, and hormone disruption in men.

An enzyme released into the bloodstream when liver cells are damaged or stressed. Elevated ALT is associated with fatty liver disease, viral hepatitis, alcohol load, and medication effects.

A liver enzyme also found in muscle, often read alongside ALT to interpret the source and pattern of liver stress. The AST-to-ALT ratio can suggest specific underlying causes.

An enzyme produced primarily in the liver and bone. Elevated levels can suggest bile-duct issues, certain liver conditions, or bone turnover, depending on the clinical context.

A liver enzyme sensitive to alcohol intake and biliary-tract stress. Elevated GGT alongside elevated ALP suggests a bile-flow problem; elevated GGT alone often reflects alcohol load or oxidative stress.

The bundled enzyme set — ALT, AST, ALP, GGT — reported together from a single sample. Reading them as a pattern carries more interpretive weight than any single enzyme on its own.

A calculation from blood creatinine that estimates how well your kidneys are filtering. The standard read on kidney function and a baseline that influences how other markers are interpreted.

A bundled panel measuring glucose, electrolytes, calcium, kidney filtration markers, liver enzymes, and protein balance. A broad organ-system foundation read most other panels are interpreted against.

The bundled kidney-specific subset — creatinine, eGFR, BUN, and electrolyte balance — reported together. Measures both filtration capacity and the downstream electrolyte regulation the kidneys manage.

A bundled panel measuring red blood cells, white blood cells across their five subtypes, platelets, and red cell size and shape. Captures oxygen-carrying capacity and the immune cell baseline in one draw.

The protein that stores iron in your body. Ferritin reflects total iron stores and can run low for months before standard hemoglobin reads as anemic — associated with fatigue, hair shedding, and reduced exercise tolerance.

Measures the amount of iron currently in circulation, distinct from the stored iron ferritin tracks. Read together with ferritin and CBC, the three markers separate functional iron deficiency from depleted iron stores.

A genetic panel testing for inherited variants associated with elevated lifetime risk of specific cancers, including variants in BRCA1, BRCA2, and Lynch syndrome genes. Results inform how cancer surveillance is approached over time and complement standard blood-marker testing.

A panel testing for inherited variants associated with familial hypercholesterolemia and other genetic patterns of cardiovascular risk. Results inform how cardiovascular markers are monitored and interpreted over time.

A genetic panel covering variants associated with inherited heart-rhythm conditions such as long QT syndrome. Particularly relevant when there is a family history of unexplained cardiac events.

A genetic panel screening for inherited susceptibility to metabolic conditions including type 2 diabetes and obesity-related variants. Provides a baseline risk read that complements metabolic blood markers.

Measures IgE antibodies — the immune class responsible for immediate, classical allergic reactions to specific foods. The standard test for diagnosing true food allergies.

Measures IgG antibodies against a panel of common foods. Some clinicians use IgG patterns alongside elimination-diet observations to evaluate delayed-onset food reactions; the framework is not universally accepted and IgG is offered as part of a broader workup rather than a stand-alone diagnostic test.

Measures IgG4 antibodies — a specific subclass associated with chronic food exposure patterns and longer-term immune tolerance. Read alongside the IgG panel for a fuller food-reactivity picture.

Measures lead exposure, which accumulates in soft tissue and bone over years. Associated with fatigue, cognitive symptoms, hypertension, and developmental concerns; common exposure routes include older plumbing, occupational dust, and imported pottery.

Measures mercury exposure from dietary sources (predominantly large fish) and occupational contact. Elevated mercury is associated with neurological symptoms, fatigue, and immune dysregulation.

Measures arsenic exposure from contaminated water, certain foods (notably rice), and industrial sources. Chronic long-term exposure is associated with cardiovascular effects, skin changes, and increased risk of some forms of cancer.

Measures cadmium exposure from tobacco smoke, industrial sources, and certain foods. Cadmium accumulates in the kidneys and is associated with renal stress and bone density loss.

Measures aluminum exposure from cookware, antiperspirants, certain medications, and industrial sources. Elevated levels are associated with neurological symptoms and kidney-clearance issues.

Measures antimony exposure, most often from industrial contact and certain consumer products. Elevated levels are associated with respiratory and cardiovascular effects.

Measures barium exposure, typically from industrial sources or contaminated water. Chronic exposure is associated with cardiovascular and gastrointestinal effects.

Measures beryllium exposure, most commonly occupational from aerospace, electronics, and metalworking industries. Associated with chronic lung disease in exposed workers.

Measures bismuth levels, most often elevated from chronic use of bismuth-containing medications. Elevated bismuth is associated with neurological symptoms in sustained-exposure cases.

Measures nickel exposure, common from jewellery, industrial contact, and certain foods. Associated with contact-dermatitis patterns and chronic inflammation in sensitized individuals.

Measures thallium exposure, rare in routine settings but possible from industrial sources or environmental contamination. Associated with neurological symptoms, hair loss, and gastrointestinal effects.

Measures uranium exposure, typically from contaminated water in specific regions or occupational contact. Chronic exposure is associated with kidney effects.

A cytokine elevated in chronic inflammatory states, including biotoxin-driven illness. One of three first-line CIRS markers used to indicate ongoing inflammatory activation.

An enzyme released during inflammatory tissue remodelling, elevated in many CIRS cases. Associated with the vascular inflammation pattern that drives many of the chronic symptoms.

A regulatory hormone that runs low in chronic biotoxin exposure. Low MSH is associated with sleep disruption, gut symptoms, and immune dysregulation.

A complement-system fragment released during immune activation. Elevated C4a is associated with the inflammatory pattern of biotoxin-driven illness and tracks symptom activity.

A signaling protein involved in vascular function and oxygen delivery. Abnormal VEGF — often low — is one of the markers described in evaluation frameworks for biotoxin-related illness, read alongside the other inflammatory markers on the panel.

The pituitary signal driving cortisol production, read in the CIRS context alongside cortisol to interpret HPA-axis disruption that often accompanies biotoxin illness.

A second cortisol read in the CIRS workup, used together with ACTH to capture rhythm patterns rather than a single morning level.

A pituitary hormone that regulates fluid balance, often dysregulated in CIRS. Abnormal ADH is associated with the thirst, frequent urination, and electrolyte patterns common in biotoxin illness.

Measures the concentration of solutes in your blood, used alongside ADH to interpret fluid and electrolyte regulation in CIRS cases.

A hormone that signals satiety and energy balance. Often elevated in CIRS and associated with the weight-regulation difficulties many patients report.

A second read on DHEA-S in the CIRS workup, used to capture HPA-axis impact in cases where adrenal function appears affected by sustained biotoxin exposure.

A second read on ferritin in the CIRS workup. Ferritin can run high as an acute-phase reactant in chronic inflammation, distinct from its more familiar role tracking iron stores.

A second read on vitamin D in the CIRS workup. Low vitamin D is associated with the immune dysregulation pattern seen in many biotoxin-illness cases.

A second read on zinc in the CIRS workup. Zinc status often shifts with chronic immune activation and tracks alongside the other inflammation markers.

An antibody against gliadin, a wheat protein. Used in the CIRS context to identify gluten-driven immune activation that can overlap with biotoxin symptoms.

A complementary antibody against gliadin in a different immune class, read alongside Antigliadin IgA to capture both recent and longer-standing gluten-related immune activity.

A genetic typing of immune-system surface markers associated with susceptibility to chronic biotoxin illness. Identifies the inherited HLA patterns linked to reduced biotoxin clearance.

A specialty test quantifying specific mycotoxins — the toxic compounds produced by mold — in serum or urine. Available as either a serum send-out or an at-home urine kit covering eleven distinct mycotoxins.
