Connect the tests
Instead of looking at numbers in isolation, see the biological chain that links them together: exactly the way a Blood Sciences Expert reads a report.
- Vitamin K → Clotting Factors → PT / INR
Risk of easy bruising or bleeding. Could come from diet, gut absorption problems, broad-spectrum antibiotics, or medications like warfarin.
- Sugar → Insulin → Weight → Cholesterol → Artery Health
This is the metabolic syndrome chain. It links pre-diabetes with heart attacks and strokes years before they happen.
- Liver → Albumin & Clotting Factors → Fluid Balance & Bleeding
A low albumin with a prolonged PT in someone with raised ALT is a warning sign of advancing liver disease.
- Thyroid → Metabolism → Heart Rate → Weight → Energy
High TSH with low T4 means an under-active thyroid, slow, cold, tired, gaining weight. Low TSH with high T4/T3 means over-active, fast heart, weight loss, anxiety.
- Kidneys → Salt & Water → Blood Pressure → Heart Work
Damaged kidneys raise blood pressure; high blood pressure damages kidneys further. A vicious circle.
- Platelets + Coagulation Factors → Clotting Ability → Bleeding Risk
Low platelets cause spotty bruising and nosebleeds. Low clotting factors cause deeper bleeding (into joints or muscle).
- Iron → Haemoglobin → Oxygen Delivery → Energy
Tiredness, breathlessness, hair loss and brittle nails. In pre-menopausal women heavy periods are the commonest cause.
