Peak Insights 70

The Peak Insights 70 is our most extensive panel, covering 70 biomarkers across cardiovascular, hormonal, metabolic, nutritional, immune and inflammatory categories. Use it to build a detailed picture of your body chemistry and to support conversations with your GP about wellness, lifestyle and longevity.

Iron & Protein Status

• Albumin: The main protein in blood, helping keep fluid inside blood vessels and carrying hormones and medicines around the body. Levels are influenced by hydration, nutrition and liver activity.

Liver & Muscle Enzymes

• Alanine Aminotransferase (ALT): A liver enzyme released when liver cells are under stress. Influenced by alcohol, certain medications, body weight and recent activity.
• Alkaline Phosphatase (ALP): An enzyme found mainly in liver and bone. Levels vary with bone turnover (growth, healing), liver activity and certain medications.

• Total Bilirubin: A pigment produced when red blood cells are recycled. Influenced by liver activity, fasting and individual genetic variation (e.g. Gilbert's pattern).
• Total Protein: The combined amount of albumin and globulin in blood plasma.
• CK (Creatine Kinase): An enzyme released by muscle activity. Levels typically rise after hard exercise, physical work or muscle strain.

Full Blood Count (FBC)

• Basophils: A type of white blood cell involved in inflammatory and allergic responses.
• Eosinophils: A type of white blood cell active in parasitic infections and allergic responses.
• Haematocrit: The proportion of blood made up of red blood cells, useful for assessing red cell volume and hydration.
• Haemoglobin: The protein in red blood cells that carries oxygen from the lungs to the rest of the body.
• Lymphocytes: White blood cells central to the immune system's adaptive response.
• MCHC (Mean Corpuscular Hemoglobin Concentration): The average concentration of haemoglobin in red blood cells.
• Mean Cell Hb (Mean Corpuscular Hemoglobin): The average amount of haemoglobin per red blood cell.
• Mean Cell Volume (MCV): The average size of red blood cells.
• Monocytes: White blood cells involved in immune surveillance and resolution of inflammation.
• MPV (Mean Platelet Volume): The average size of platelets, used alongside platelet count to understand clotting activity.
• Neutrophils: The most common type of white blood cell, involved in fighting infection and supporting tissue repair.
• Platelets: Small blood cells essential for clotting and wound healing.
• Red Blood Cells: Cells that carry oxygen around the body. Influenced by iron status, hydration, altitude and recent activity.

Inflammation & Immune Markers

• HsCRP (High-sensitivity C-reactive Protein): A sensitive marker of inflammation. Influenced by recent infection, injury, lifestyle and chronic inflammatory activity.
• Uric Acid: A by-product of how the body processes purines from food. Influenced by diet (especially red meat and alcohol), hydration and kidney activity.
• IgE (Total): An immune antibody involved in allergic and parasitic responses. Levels vary with individual immune patterns and environmental exposures.

Reproductive Hormones

• Follicle Stimulating Hormone (FSH): A pituitary hormone that supports egg development in women and sperm production in men. Levels vary across the menstrual cycle and life stages.
