An enzyme found in the liver, bones, kidneys, and digestive system. Elevated ALP can indicate bile duct obstruction, liver disease, or bone disorders. It's normally higher in children and during pregnancy due to bone growth.

An electrolyte that works with sodium to maintain fluid balance, blood pressure, and acid-base balance. Chloride abnormalities often accompany sodium abnormalities and can indicate dehydration, kidney disease, or metabolic disorders.

An enzyme found in the liver, heart, and muscles. While less liver-specific than ALT, elevated AST can indicate liver damage, heart attack, or muscle injury. The AST/ALT ratio helps distinguish between different liver conditions.

A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.

Measures the total CO2 content in blood, primarily as bicarbonate. It reflects the acid-base balance maintained by the lungs and kidneys. Abnormal levels can indicate respiratory or metabolic acidosis or alkalosis.

A critical electrolyte for heart rhythm, muscle contractions, and nerve function. Both high and low potassium can cause dangerous cardiac arrhythmias. Levels are influenced by kidney function, medications, and diet.

The primary electrolyte regulating fluid balance and blood pressure. Sodium is essential for nerve impulses and muscle contractions. Abnormal levels can cause confusion, seizures, and cardiac arrhythmias.

Blood sugar — the body's primary energy source. Fasting glucose screens for diabetes and prediabetes. Chronically elevated glucose damages blood vessels and organs. Levels fluctuate with meals, stress, and physical activity.

The most common type of fat in the body, stored for energy. Elevated triglycerides — often from excess sugar, alcohol, or calories — increase cardiovascular risk and can cause pancreatitis at very high levels.

Blood sugar — the body's primary energy source. Fasting glucose screens for diabetes and prediabetes. Chronically elevated glucose damages blood vessels and organs. Levels fluctuate with meals, stress, and physical activity.

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Ratio of omega-3 fatty acid (EPA) to omega-6 fatty acid (AA); informs diet quality.

Omega-6 fatty acid found in various foods.

Omega-3 fatty acid found in fish; involved in brain function, growth, and reducing inflammation.

Omega-3 fatty acid found in fish; involved in brain function, growth, and reducing inflammation.

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Measures the combined amount of albumin and globulin proteins in your blood. These proteins are essential for fighting infections, blood clotting, and transporting substances throughout the body.

The ratio of albumin to globulin proteins in blood. A low A/G ratio may indicate overproduction of globulins (as in multiple myeloma or autoimmune disease) or underproduction of albumin (liver disease).

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Measures levels of omega-3 and omega-6 fatty acids, including total omega-3, total omega-6, EPA + DPA + DHA, Arachidonic Acid/EPA Ratio, and Omega-6/Omega-3 Ratio.

The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.

A mineral essential for oxygen transport (in hemoglobin), energy production, and immune function. Serum iron measures the amount circulating in blood, but ferritin and TIBC provide a more complete picture of iron status.

Precursor to vitamin A; functions as an antioxidant.

Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.

A fat-soluble antioxidant that protects cell membranes from oxidative damage. Vitamin E works synergistically with vitamin C and selenium. Deficiency is rare but can cause nerve and muscle damage.

The best indicator of overall vitamin D status. Vitamin D is essential for calcium absorption, bone health, immune function, and mood regulation. Deficiency is extremely common, especially in northern latitudes, and linked to increased disease risk.

A toxic heavy metal found in certain fish (methylmercury), dental amalgams, and industrial sources. Mercury targets the nervous system, causing tremors, cognitive changes, and sensory impairment. Fish consumption is the primary source for most people.

Vitamin B9 (Folate) is crucial for DNA synthesis and repair. Low levels can lead to anemia and other health issues.

The primary iron storage protein. Ferritin reflects total body iron stores and is the first marker to drop in iron deficiency. However, ferritin also rises with inflammation, infection, and liver disease, which can mask true iron deficiency.

Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels can lead to jaundice and indicate liver or bile duct problems.

Osmolality measures the concentration of dissolved particles in the blood, indicating hydration status.

A waste product from normal muscle metabolism, filtered by the kidneys. Blood creatinine levels reflect kidney filtration capacity. Elevated levels may indicate impaired kidney function, dehydration, or excessive muscle breakdown.

A waste product from protein breakdown, processed by the liver and excreted by the kidneys. Elevated urea levels can indicate kidney dysfunction, dehydration, high-protein diet, or gastrointestinal bleeding.

A waste product from normal muscle metabolism, filtered by the kidneys. Blood creatinine levels reflect kidney filtration capacity. Elevated levels may indicate impaired kidney function, dehydration, or excessive muscle breakdown.

An estimated measure of how well your kidneys filter waste from the blood. It's calculated from creatinine levels, age, sex, and race. eGFR is the primary marker used to stage chronic kidney disease.

The combined measure of all cholesterol in your blood, including HDL, LDL, and VLDL. While useful as an overview, the breakdown between HDL and LDL is more clinically meaningful for assessing cardiovascular risk.

Non-HDL cholesterol is the total cholesterol minus HDL cholesterol, representing all "bad" cholesterols. High levels can increase the risk of heart disease.

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
