CBC, LFT, RFT, HbA1c — what do these letters actually mean? A plain-language guide to common tests.
A Complete Blood Count (CBC) looks at your red cells, white cells and platelets. It can reveal anaemia, infection or clotting issues.
Liver Function Tests (LFT) and Renal Function Tests (RFT) check how well your liver and kidneys are working — important for many chronic conditions and before surgery.
HbA1c reflects your average blood sugar over the past three months, giving a clearer picture of diabetes control than a single reading.
Reference ranges are a guide, not a diagnosis. Always review results with your doctor, who considers them alongside your symptoms and history.
