What’s included in this test

Clotting status
Mean Platelet Volume (MPV)
MPV reflects the average size of your platelets. It provides insight into platelet production and activity, and can help assess risk of clotting or bleeding disorders.
Red blood cells
Red Cell Distribution Width (RDW)
RDW measures the variation in size of your red blood cells. It helps identify types of anaemia and can indicate nutrient deficiencies such as iron, B12, or folate.
Cardiac health
Triglycerides
Triglycerides are a type of fat found in your blood. Elevated levels can increase the risk of heart disease and often indicate poor dietary or metabolic health.
HDL/Cholesterol Ratio
This ratio compares ‘good’ HDL cholesterol to total cholesterol. A higher ratio indicates a healthier balance and lower cardiovascular risk.
Iron markers
Transferrin Saturation
Transferrin saturation shows the percentage of transferrin that is bound with iron. It's a sensitive marker for diagnosing iron deficiency or haemochromatosis.
TIBC
TIBC measures the total capacity of transferrin to carry iron. It helps determine whether iron levels in the blood are too low or too high.
UIBC
UIBC reflects the reserve capacity of transferrin to bind iron. It's used alongside other iron studies to investigate iron deficiency or excess.
Transferrin
Transferrin is a protein that transports iron in your blood. Measuring its levels helps assess iron deficiency or overload and supports anaemia diagnosis.
White blood cells
Monocytes (Mo)
Monocytes assist in clearing infections and dead cells. Elevated levels may indicate chronic inflammation or certain infections.
Lymphocytes (Ly)
Lymphocytes help fight viral infections and are vital to your immune memory. Abnormal levels can be seen in viral illnesses or immune disorders.
Neutrophils (Ne)
Neutrophils are your body’s first line of defense against infection. High levels usually indicate bacterial infections or inflammation.
Basophils (Ba)
Basophils are white blood cells that release histamine during allergic responses. They are rarely elevated but may increase in certain chronic inflammatory conditions.
Eosinophils (Eo)
Eosinophils are a type of white blood cell involved in allergic reactions and fighting parasites. Elevated levels may suggest allergy, asthma, or parasitic infection.
Clotting status
Platelets (PLT)
Platelets are responsible for blood clotting. Low levels may lead to bleeding, while high levels can increase the risk of thrombosis.
Red blood cells
Mean Corpuscular Haemoglobin Concentration (MCHC)
MCHC shows the concentration of haemoglobin in your red blood cells. It's useful in evaluating anaemia types and red cell colour (hypochromia).
Mean Corpuscular Haemoglobin (MCH)
MCH indicates the average amount of haemoglobin in each red blood cell. Abnormal levels help identify different forms of anaemia.
Mean Corpuscular Volume (MCV)
MCV reflects the average size of your red blood cells. It helps classify types of anaemia — whether cells are too large, too small, or just right in size.
Haematocrit (HCT)
HCT shows the percentage of blood made up of red blood cells. It helps assess anaemia, dehydration, and overall blood volume status.
White blood cells
White Blood Cells (WBC)
WBC count indicates immune system activity. Elevated levels can suggest infection or inflammation, while low levels may reflect bone marrow suppression or immune deficiency.
Red blood cells
Red Blood Cells (RBC)
RBC count measures the number of red blood cells in your blood. It's key to assessing oxygen-carrying capacity and diagnosing anaemia or bone marrow issues.
Haemoglobin (Hb)
Haemoglobin carries oxygen from your lungs to the rest of your body. Low levels may indicate anaemia, while high levels could signal dehydration or other blood disorders.
Kidney health
eGFR (estimated Glomerular Filtration Rate)
eGFR estimates how well your kidneys are filtering waste from your blood. It's a key indicator of kidney function and is especially useful for early detection of chronic kidney disease (CKD).
Tumour markers
Prostate specific antigen (PSA)
Total PSA is a key marker for prostate health, often elevated in cancer, benign enlargement, or infection. Used for early detection and monitoring.
Thyroid health
Free T4
Free T4 gives insight into the level of unbound thyroxine hormone. It’s key for diagnosing thyroid conditions when TSH alone is inconclusive.
Thyroglobulin Antibody
Thyroglobulin Antibody testing helps diagnose autoimmune thyroid disorders and monitor patients post-thyroid cancer treatment.
Thyroglobulin
Thyroglobulin is a protein produced by the thyroid gland. It’s often monitored in thyroid cancer follow-up or to assess thyroid gland activity.
Thyroid peroxidaise (TPO) antibodies
TPO antibodies indicate autoimmune thyroid disease such as Hashimoto’s or Graves’. Useful in unexplained fatigue, weight gain, or thyroid symptoms.
TSH
TSH controls the thyroid gland’s hormone production. It’s the most common marker for identifying thyroid dysfunction, such as hypothyroidism.
Hormone health
Cortisol
Cortisol is your body’s primary stress hormone. Abnormal levels can indicate adrenal fatigue, Cushing’s syndrome, or Addison’s disease.
Progesterone level
Progesterone helps regulate menstrual cycles and supports early pregnancy. This test confirms ovulation and assesses fertility.
Follicle stimulating hormone level (FSH)
FSH regulates reproductive processes and is essential for fertility. It’s used to assess ovarian reserve in women or testicular function in men.
Luteinising hormone (LH)
Luteinising Hormone (LH) plays a critical role in ovulation and testosterone production. It's commonly tested in fertility and hormonal evaluations.
Prolactin
Prolactin is a hormone primarily involved in lactation but also impacts fertility and menstrual cycles. High levels can suggest pituitary issues.
Sex hormone binding globulin level (SHBG)
SHBG regulates the availability of sex hormones like testosterone and oestradiol. Abnormal levels can indicate hormonal imbalance or liver dysfunction.
PTH (Parathyroid Hormone)
PTH helps regulate calcium and phosphate balance in the blood. This test helps detect parathyroid disorders and bone metabolism issues.
Blood sugar
Insulin
Insulin testing provides insight into how your body regulates blood sugar. It's especially useful in assessing risk for insulin resistance or metabolic syndrome.
Thyroid health
Free T3
Free T3 is the active form of triiodothyronine, a thyroid hormone. It’s useful in identifying hyperthyroidism or ineffective thyroid conversion.
Hormone health
Testosterone
Testosterone testing measures total testosterone levels to assess libido, mood, and metabolic function in both men and women.
Dehydroepiandrosterone sulphate (DHEA-S)
DHEA-S is a precursor hormone involved in producing sex hormones. Abnormal levels can suggest adrenal issues or hormonal imbalance.
Oestradiol
Oestradiol is the primary form of estrogen in women. This test is essential in fertility assessments, menstrual irregularities, or hormone replacement therapy.
Testosterone Free
Free Testosterone provides an estimate of biologically active testosterone, useful in diagnosing hormonal imbalances not reflected in total testosterone alone.
Blood sugar
Glucose
Glucose testing measures blood sugar levels at a specific point in time. It's essential for screening diabetes and assessing metabolic health during routine check-ups.
Liver health
Alanine Aminotransferase (ALT)
Alanine Aminotransferase (ALT) is an enzyme mainly found in the liver. Elevated levels can indicate liver damage from conditions like hepatitis or fatty liver disease.
Cardiac health
Apolipoprotein A1 (APO A1)
APO A1 is a protein component of HDL cholesterol. Higher levels are protective against cardiovascular disease and indicate good lipid metabolism.
Liver health
Bilirubin (Total)
Total bilirubin helps assess liver function and red blood cell breakdown. High levels can cause jaundice and indicate liver or gallbladder issues.
Electrolytes
Magnesium
Magnesium supports muscle and nerve function, blood sugar control, and bone health. Deficiency is linked to cramps, fatigue, and irregular heartbeat.
Liver health
Albumin
Albumin is a major protein in the blood, essential for maintaining fluid balance and transporting nutrients. Low levels can signal liver or kidney disease.
Kidney health
Bicarbonate
Bicarbonate helps regulate your body’s pH balance. It's tested when evaluating acid-base disorders or respiratory conditions.
Sodium
Sodium is critical for fluid balance, nerve function, and blood pressure regulation. Abnormal levels can point to kidney, adrenal, or hydration issues.
Liver health
Total protein
Total protein includes albumin and globulin. It's used to assess liver function, kidney health, and nutritional status.
