• ABO Group Identifies your blood type (A, B, AB, or O) based on antigens on your red blood cells. Essential for safely matching blood for transfusions or transplants.
• Absolute CD19+ Cells Counts the number of CD19+ B cells per volume of blood, the immune cells that make antibodies, used to assess immune system health.
• Absolute CD3+ Cells Counts the number of CD3+ T cells per volume of blood, the main immune cells that direct and carry out immune responses, to assess immune health.
• Absolute CD4+ Cells Counts CD4 'helper' T-cells, a key part of your immune system. Widely used to monitor immune health in HIV and other immune conditions.
• Absolute CD8+ Cells Counts CD8 'cytotoxic' T-cells, immune cells that help destroy infected or abnormal cells. Used to assess immune status.
• Acacia (t19) IgE Measures IgE antibodies to acacia tree pollen, used to check for allergic sensitization that may explain your symptoms.
• Acarus Siro (d70) IgE Measures IgE antibodies to Acarus siro, a storage mite, used to check for allergic sensitization that may explain your symptoms.
• Acremonium Kiliense (C. Acremonium) (m202) IgE Measures IgE antibodies to the mould Acremonium kiliense, used to check for allergic sensitization that may explain your symptoms.
• Activated Partial Thromboplastin TimeaPTT Measures how long it takes your blood to clot through one of its main pathways. Used to check for bleeding disorders and monitor blood-thinning medications like heparin.
• Activated Protein C Resistance Checks whether your blood resists the natural anticlotting action of activated protein C, most often caused by the inherited factor V Leiden variant.
• Adiponectin A hormone released by fat cells that helps regulate blood sugar and fat breakdown. Higher levels are generally linked to better insulin sensitivity and metabolic health.
• Adrenocorticotropic HormoneACTH A pituitary hormone that signals your adrenal glands to produce cortisol. Helps determine whether abnormal cortisol levels stem from the pituitary, adrenal glands, or elsewhere.
• Alanine AminotransferaseALT A liver enzyme released into the blood when liver cells are damaged. One of the main markers used to screen for liver inflammation or injury.
• Albumin The main protein made by your liver, which helps balance fluids and carries hormones, vitamins, and medications through your blood. Low levels can point to liver, kidney, or nutrition issues.
• Albumin, 24 Hour Measures the total albumin your kidneys pass into urine over 24 hours, used to detect and monitor early kidney damage.
• Albumin/Creatinine Ratio, Random A ratio of albumin to creatinine in a single urine sample, used to screen for and monitor early kidney damage without a 24-hour collection.
• Albumin/Globulin Ratio Compares your two main blood protein types, albumin and globulin. An abnormal ratio can point toward liver disease, kidney problems, or immune system conditions.
• Albumin, Urine (Timed) Measures albumin in urine collected over a set period of time, used to look for and monitor early kidney damage.
• Alder (t2) IgE Measures IgE antibodies to alder tree pollen, used to check for allergic sensitization that may explain your symptoms.
• Aldolase An enzyme involved in breaking down sugar for energy, found mainly in muscle. Elevated levels can indicate muscle damage or certain muscle diseases.
