Lab reports can look intimidating — rows of abbreviations, reference ranges, and numbers that mean little without context. But understanding the basics of what's being measured can help you have a more informed conversation with your doctor. Here's a plain-language walkthrough of some of the most commonly ordered tests.

Full Haemogram (FHG / CBC)

This is one of the most frequently ordered tests, measuring red blood cells, white blood cells, haemoglobin and platelets. In broad terms: low haemoglobin can indicate anaemia, a high white blood cell count often signals infection or inflammation, and platelet levels relate to how well your blood can clot. A single abnormal value rarely tells the whole story — your clinician interprets it alongside your symptoms and history.

Renal and Liver Function Tests (RFTs & LFTs)

These panels check how well your kidneys and liver are working, measured through markers like creatinine, urea, and liver enzymes. They're often ordered as a baseline check, before starting certain medications, or to monitor existing conditions like hypertension or diabetes that can affect these organs over time.

Blood Sugar Tests (FBS, RBS, HbA1c)

Fasting Blood Sugar (FBS) and Random Blood Sugar (RBS) give a snapshot of your blood glucose at the moment of testing. HbA1c is different — it reflects your average blood sugar over the past two to three months, which is why it's commonly used to monitor diabetes management rather than diagnose a single high reading.

A result outside the reference range isn't automatically a diagnosis Reference ranges are statistical averages, and some variation is normal. Your clinician looks at your results in the context of your symptoms, history and sometimes repeat testing — never interpret a single abnormal value in isolation.

Lipid Profile

This measures cholesterol and triglycerides — key markers for cardiovascular health. It's typically broken down into LDL ("bad" cholesterol), HDL ("good" cholesterol), and triglycerides. Results here are usually considered alongside other risk factors like age, blood pressure, and family history, not as a standalone verdict.

Serology & Infection Screening

Tests like Hepatitis B/C screening, VDRL, and H. pylori antigen testing look for markers of specific infections. These are often part of routine antenatal screening, pre-employment checks, or investigation of specific symptoms. A positive result typically prompts further confirmatory testing and a conversation with your doctor about next steps — it's rarely the final word on its own.

Reading Your Report

Most lab reports show three things: the test name, your result, and a reference range (the typical range for a healthy person). Results flagged as "H" (high) or "L" (low) simply mean outside that reference range — not necessarily a cause for alarm. This is exactly why results are reviewed with a clinician rather than self-interpreted: the same number can mean different things depending on your age, sex, symptoms and medical history.

When results need follow-up If any test comes back significantly outside the normal range, our clinical team will reach out to discuss next steps — whether that's a repeat test, further investigation, or starting treatment. Always complete the follow-up conversation rather than acting on a result alone.

Our in-house laboratory at RKA Specialist Hospital covers haematology, biochemistry, immunology, serology, parasitology and microbiology — with most results available the same day, so your doctor can discuss them with you before you leave.
