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.

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.

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.

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.

The percentage of white blood cells that are basophils. Basophils play a role in allergic reactions by releasing histamine and other inflammatory mediators.

A key component of the body's acid-base buffering system. Bicarbonate levels reflect the balance between acids and bases in the blood. Abnormal values help diagnose metabolic acidosis or alkalosis.

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.

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.

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.

A protein produced by the liver in response to inflammation. CRP rises rapidly during infection, injury, or inflammatory conditions. It's a general marker — elevated CRP signals inflammation but doesn't pinpoint the source.

An enzyme found primarily in muscle tissue (skeletal and cardiac). Elevated CK indicates muscle damage from exercise, injury, or disease. Very high levels can indicate rhabdomyolysis, a potentially dangerous breakdown of muscle tissue.

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.

The percentage of white blood cells that are eosinophils. Elevated eosinophil percentages are commonly associated with allergic reactions and parasitic infections.

Erythrocyte sedimentation rate — measures how quickly red blood cells settle to the bottom of a test tube. Faster settling indicates more inflammation. ESR is a non-specific marker used to monitor inflammatory conditions like arthritis and vasculitis.

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 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.

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.

The unbound, active form of the main thyroid hormone T4. Free T4 directly reflects thyroid gland output and is used alongside TSH to diagnose and monitor thyroid disorders.

A liver enzyme sensitive to alcohol use and bile duct problems. GGT is often the first liver enzyme to rise when bile ducts are blocked. Combined with ALP, it helps determine whether elevated ALP is from liver or bone.

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.

The percentage of your blood volume occupied by red blood cells. It reflects the balance between red blood cell production and loss, helping diagnose anemia, dehydration, and polycythemia.

The iron-rich protein in red blood cells responsible for carrying oxygen throughout your body and returning carbon dioxide to the lungs. Low haemoglobin is the primary marker for anemia and can cause fatigue, weakness, and shortness of breath.

Often called 'good' cholesterol, HDL carries cholesterol away from arteries back to the liver for removal. Higher HDL levels are protective against heart disease. Exercise, healthy fats, and moderate alcohol intake can raise HDL.

Lactate Dehydrogenase (LDH) is an enzyme that helps break down glucose in your muscles. High levels can indicate tissue damage or disease.

The percentage of white blood cells that are lymphocytes, key players in adaptive immunity including antibody production and cell-mediated immune responses.

The average concentration of hemoglobin within each red blood cell. It helps differentiate types of anemia — low MCHC points to iron deficiency, while high MCHC can indicate spherocytosis.

The average amount of hemoglobin in each red blood cell. Low MCH indicates that red blood cells carry less oxygen than normal, commonly seen in iron-deficiency anemia.

The average size of your red blood cells. Small cells (microcytic) suggest iron deficiency, while large cells (macrocytic) may indicate vitamin B12 or folate deficiency. Normal-sized cells with low count suggest chronic disease.

The percentage of white blood cells that are monocytes. Monocytes are part of the innate immune system and develop into macrophages and dendritic cells in tissues.

The percentage of white blood cells that are neutrophils. Neutrophils are the most common WBC type and respond primarily to bacterial infections.

A mineral essential for bone formation, energy metabolism (ATP), and acid-base balance. Phosphate levels are inversely related to calcium and regulated by parathyroid hormone and vitamin D.

Measures the number of platelets, small cell fragments essential for blood clotting. Low platelets increase bleeding risk, while high platelets may increase clot risk. Important for monitoring clotting disorders and medication effects.

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.

Measures the variation in size among your red blood cells. A high RDW means your red blood cells vary significantly in size, which can help distinguish between different types of anemia.

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.

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.

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 percentage of transferrin (iron-transporting protein) that is carrying iron. Calculated from serum iron and TIBC. Low saturation indicates iron deficiency; high saturation may indicate hemochromatosis (iron overload).

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.

The primary screening test for thyroid function. TSH is produced by the pituitary gland to regulate thyroid hormone production. High TSH indicates an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism).

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 the breakdown of purines (found in certain foods and body cells). High levels can form crystals in joints (gout) or kidneys (kidney stones). Also associated with cardiovascular disease and metabolic syndrome.

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.

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.
