Red blood cells, white blood cells, platelets, haemoglobin, haematocrit, MCV, MCH, MCHC, neutrophils, lymphocytes, monocytes, eosinophils, basophils. Your blood count is the foundation of any serious health assessment. It reveals immune function, oxygen-carrying capacity, clotting ability, and signs of infection, anaemia, or blood disorders — many of which cause no symptoms in their early stages.

Iron, ferritin, transferrin, TIBC (total iron binding capacity), transferrin saturation. Iron deficiency is one of the most common nutritional problems in the UK — and one of the most frequently missed. Ferritin, the storage form of iron, can be depleted for months or years before standard haemoglobin levels fall. If you experience fatigue, brain fog, or poor exercise recovery, iron status is often the first place to look.

Total cholesterol, LDL, HDL, triglycerides, total cholesterol/HDL ratio. A standard NHS cholesterol check typically measures three or four numbers. This panel includes the full lipid profile plus the cholesterol/HDL ratio — a more accurate predictor of cardiovascular risk than total cholesterol alone.

Glucose, HbA1c. HbA1c reflects your average blood sugar over the past two to three months — a far more reliable indicator of metabolic health than a single fasting glucose reading. Pre-diabetic patterns often persist for years before any symptoms appear, and early detection is when intervention is most effective.

Creatinine, eGFR (estimated glomerular filtration rate), urea. Your kidneys filter around 200 litres of blood every day. Declining kidney function is frequently asymptomatic until it is significantly advanced. eGFR is the key marker of filtration efficiency — and it is rarely tested in routine GP appointments unless there is already a known concern.

Calcium (adjusted), chloride, magnesium, phosphate, potassium, sodium. Electrolyte imbalances affect nerve conduction, muscle function, hydration, and heart rhythm. Magnesium deficiency in particular is extremely common and strongly associated with fatigue, poor sleep, muscle cramps, and anxiety — yet it is almost never tested in standard NHS blood panels.

ALT, ALP, AST, GGT, total bilirubin, albumin. A full liver panel assessing six markers of liver health — covering inflammation, cellular damage, bile duct function, and synthetic capacity. GGT is a particularly sensitive early marker of liver stress from alcohol, medication, or metabolic strain.

Vitamin D, vitamin B12, folic acid, zinc. Public Health England estimates that around 1 in 5 adults in the UK have low vitamin D levels. B12 deficiency — particularly common in people over 50, vegetarians, and those on certain medications — can cause neurological symptoms, fatigue, and mood changes that are often misattributed to other causes. Zinc deficiency affects immune function, wound healing, and hormonal balance.

High sensitivity CRP (hsCRP), CRP. Chronic low-grade inflammation is now understood to be a primary driver of most major age-related diseases — cardiovascular disease, type 2 diabetes, dementia, and cancer. hsCRP is one of the most sensitive available blood markers for detecting this inflammation before it causes damage.
