See what your bloodwork may reveal.

Measures the total amount of testosterone in your blood, including the fractions bound to proteins and the unbound fraction. The standard read on testosterone production.

The fraction of testosterone not bound to SHBG, distinct from the total testosterone read. Free testosterone reflects the portion most readily available to tissues and can be useful when SHBG is high or low enough to make the total testosterone number misleading on its own.

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.

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.

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 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.

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.

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 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.

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.

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.

Measures IgM antibodies against Borrelia, the bacterial genus that includes the species causing Lyme disease. IgM antibodies are associated with more recent immune activation; results are interpreted alongside clinical context because IgM can cross-react with other exposures.

Measures IgG antibodies against Borrelia, the immune class that develops later and persists. IgG is associated with longer-standing exposure or established infection.

A complement fragment released during immune activation, read in the Lyme workup as part of the inflammatory-response signature. Elevated C3a is associated with ongoing immune activity.
