HDL
High-density lipoprotein or "good" cholesterol, helps remove bad cholesterol, reducing heart disease risk. Low levels increase cardiovascular risk, important for heart health assessment.
Nutritional health
Heart health
hs-CRP
High-sensitivity C-reactive protein, indicates inflammation and predicts cardiovascular disease risk. High levels suggest increased risk of heart disease and inflammation, important for cardiovascular risk assessment.
Immune health
Heart health
Iron
Essential for haemoglobin production and oxygen transport. Abnormal levels indicate iron deficiency anaemia or iron overload. Tested when screening for and managing iron metabolism disorders.
LDL
Low-density lipoprotein or "bad" cholesterol, contributes to arterial plaque buildup, increasing heart disease risk. High levels are a major cardiovascular risk factor, important for managing heart health.
Nutritional health
Heart health
Luteinising Hormone (LH)
Hormone regulating sex hormone production, important for checking fertility, menstrual irregularities, and pituitary disorders. Abnormal levels indicate reproductive health issues, guiding fertility treatment.
Hormone health
Magnesium (Serum)
Essential mineral for nerve, muscle function, and enzyme reactions. Abnormal levels indicate dietary deficiency, kidney disease, or metabolic disorders, important for testing and managing electrolyte imbalances.
Bone & muscle
Mean Corpuscular Haemoglobin Concentration (MCHC)
Measures haemoglobin concentration in red blood cells, indicating the cells' oxygen-carrying capacity. Abnormal levels help check for different types of anaemia, guiding treatment and management.
Monocytes
Type of white blood cell involved in immune response. Elevated levels indicate chronic inflammation, infection, or hematologic disorders. Used when screening for immune system and blood diseases.
Omega 6: Omega 3 Ratio
Reflects balance between pro-inflammatory and anti-inflammatory fatty acids. Imbalances can contribute to chronic diseases. Optimal ratios are crucial for reducing inflammation and promoting heart health.

Platelet Count
Measures clotting cells in the blood. Platelet count is tested when screening for bleeding disorders, thrombocytopenia, or thrombocythemia. Abnormal counts can indicate bone marrow problems, increased bleeding risk, or clotting disorders.
Progesterone
Hormone critical for regulating the menstrual cycle and maintaining pregnancy. Abnormal levels can indicate ovulation issues, infertility, or pregnancy complications, important for reproductive health assessment.
Hormone health
Prolactin
A stress hormone; high levels can indicate hard exercise training, pituitary tumors, hypothyroidism, or pregnancy. Tested when screening for reproductive disorders and managing pituitary function.
Hormone health
Red Blood Cell (RBC)
Transports oxygen throughout the body. Abnormal counts indicate anaemia, dehydration, or polycythaemia. Used when screening for blood volume and oxygenation issues.
Nutritional health
Immune health
Sex Hormone Binding Globulin (SHBG)
Binds sex hormones, regulating their activity. Abnormal levels suggest hormonal imbalances, affecting conditions like polycystic ovary syndrome or hypogonadism, important for assessing hormonal status.
Hormone health
Sodium
Essential electrolyte for fluid balance, nerve, and muscle function. Abnormal levels indicate dehydration, kidney disease, or hormonal imbalances. Tested when screening for and managing electrolyte disorders.

What are biomarkers?
Biomarkers refer to biological molecules found in your blood that are a sign of a normal or abnormal process, or a condition or disease. They can be used for screening and disease progression monitoring, and to guide and assess treatment responses.
For example, hs-CRP levels in the blood can be used as a biomarker for inflammation, while cholesterol levels can indicate heart disease risk. You can also track hormone levels in your blood to monitor things like perimenopause, PCOS and fertility. You can view all of our home blood tests here.
