Proactively Monitor Key Biomarkers for Early Detection and Optimal Wellbeing

The Basic Health Screen is a blood test that assesses your overall health. By taking the test, you can proactively monitor your health to detect potential issues at an early stage. Gain a deeper understanding of your body, and make informed decisions about your lifestyle, diet, and healthcare choices. By regularly taking the test, stay ahead of health risks, implement preventive measures, and optimise your wellbeing.

What it includes

  • A blood test conducted by a healthcare professional at our clinic.
  • Doctor-reviewed results with written comments and advice provided.
  • Optional results consultation with a doctor is available at a discounted rate.
  • Please scroll down the page for a complete list of biomarkers included in the test.

Why take a Basic Health Screen

  1. A Basic Health Screen allows for early detection and proactive management of potential health issues, promoting a longer and healthier life.
  2. You can reduce the likelihood of developing certain conditions through this preventative approach.

Age restriction on blood tests

We're unable to offer blood tests for those under the age of 18 unless it is part of a routine GP appointment and the clinician believes it suitable.

The Basic Health Screen evaluates the following biomarkers:

Full Blood Count

  • Basophils: A white blood cell that plays a role in the body's immune response to allergies.
  • Eosinophils: A white blood cell that plays a role in the body's immune response to allergies and parasitic infections.
  • Haematocrit: The proportion of red blood cells in the blood can indicate whether a person is anaemic or dehydrated.
  • Haemoglobin: The protein in red blood cells that carries oxygen throughout the body.
  • Lymphocytes: A white blood cell that plays a key role in the body's immune system, fighting viral infections and cancers.
  • MCH: The average amount of haemoglobin in each red blood cell.
  • MCHC: The average concentration of haemoglobin in each red blood cell.
  • MCV: The average size of red blood cells, which can help diagnose specific types of anaemia.
  • Monocytes: A white blood cell that plays a role in the immune system by engulfing and digesting foreign particles, such as bacteria and viruses.
  • MPV: The average size of platelets in the blood can indicate whether a person is at risk of bleeding or clotting disorders.
  • Neutrophils: A white blood cell that fights bacterial infections.
  • Platelet count: The total number of platelets in the blood responsible for clotting and preventing bleeding.
  • RDW: The variation in the size of red blood cells can help diagnose specific types of anaemia.
  • Red cell count: A count of red blood cells in the blood, indicating whether a person is anaemic.
  • White cell count: A count of the total number of white blood cells in the blood, which can indicate infection or inflammation in the body.
  • Glucose: Vital energy source for the body. Raised glucose levels can detect insulin resistance.

Heart health profile

  • HDL and LDL cholesterol: HDL (good) and LDL (bad) cholesterol are measured to assess cholesterol levels.
  • Triglycerides: a measure of the actual fat in your blood.
  • CRP-hs: a marker for inflammation in the body.
  • Lipoprotein (a) or Lp(a): a genetic variation of LDL cholesterol that is a significant risk factor for the early development of fatty deposits in arteries.
  • Apolipoproteins A to E: proteins that attach to fats in our blood. High levels of ApoA are protective against heart disease. In contrast, high levels of ApoB represent a higher risk of heart disease. ApoE test evaluates genetic susceptibility to Alzheimer's disease.
  • High-sensitivity C-reactive protein (hsCRP): A biomarker used to measure inflammation levels in the body. It aids in assessing the risk of cardiovascular disease and provides valuable information for preventive strategies.

Kidney health

  • Blood Urea Nitrogen (BUN): A measure of urea nitrogen in the blood. It helps assess kidney function and hydration status. The biomarker indicates BUN levels, aiding in diagnosing kidney and liver diseases, dehydration, and evaluating kidney function.
  • Creatinine: A waste product produced by muscles from creatine. It helps assess kidney function and muscle health. The biomarker indicates creatinine levels, aiding in detecting and monitoring kidney diseases and evaluating renal function.
  • Estimated Glomerular Filtration Rate (eGFR): A calculation of kidney function by measuring the rate at which the kidneys filter blood. The biomarker assesses renal function, helps diagnose and monitor kidney disease, and guides medication dosing.
  • Phosphorus: An essential mineral involved in energy production, DNA synthesis, and bone formation. The biomarker indicates phosphorus levels, assisting in diagnosing and monitoring conditions related to bone health, kidney function, and metabolic disorders.
  • Serum Calcium: By measuring calcium levels in the blood, the test helps assess bone health, nerve function, and muscle contraction. The biomarker indicates serum calcium levels, aiding in diagnosing calcium-related disorders, such as osteoporosis, kidney disease, and parathyroid disorders.
  • Serum Electrolytes: Minerals in the blood that help maintain fluid balance, nerve function, and muscle contraction. The biomarker indicates electrolyte levels (sodium, potassium, chloride) and aids in assessing hydration status and kidney function and identifying electrolyte imbalances.
  • Urine Microalbumin: Measuring small amounts of albumin in the urine helps detect early kidney damage in conditions like diabetes. The biomarker indicates microalbumin levels, aiding in monitoring kidney health and identifying kidney disease at an early stage.
  • Urine Protein: The biomarker indicates protein levels in urine, aiding in diagnosing and monitoring kidney disorders, such as glomerulonephritis or kidney damage caused by diabetes or hypertension.

Liver health profile

  • Albumin: A protein the liver produces that helps transport substances in the blood. Low levels can indicate liver damage or disease.
  • Bilirubin: A yellowish pigment produced during the breakdown of red blood cells. High levels can indicate liver disease or a blocked bile duct.
  • Gamma-GT (GGT): An enzyme in the liver that is elevated in people with liver disease, heavy drinkers, and those taking certain medications.
  • Hepatitis markers: Indicators used to diagnose and monitor hepatitis infections. They help detect specific antibodies or antigens related to different types of hepatitis viruses. These biomarkers aid in identifying the presence and progression of viral hepatitis infections.
  • Liver enzymes: Proteins released by the liver during cellular processes. They help assess liver function and detect liver damage or diseases. The biomarker indicates levels of specific enzymes like ALT, AST, and ALP, aiding in diagnosing liver conditions and monitoring treatment response.
  • Prothrombin time (PT): Measures the time for blood to clot. It assesses the functioning of the clotting factors in the blood. The biomarker indicates PT values, aiding in monitoring anticoagulant therapy, detecting bleeding disorders, and evaluating liver function.
  • Total protein: Measures the total amount of protein in your blood. Low levels can indicate liver disease.
