Full Blood Count (FBC): Your Blood Cell Report Card
A Full Blood Count is one of the most commonly ordered blood tests. It measures three main cell types. Haemoglobin (Hb) carries oxygen — normal is 13-17 g/dL for men, 12-16 g/dL for women. Low haemoglobin indicates anaemia, causing fatigue and breathlessness. Common causes include iron deficiency, thalassemia trait (common in Malaysia), and chronic disease. White Blood Cell count (WBC) is your infection-fighting army — normal is 4,000-11,000/uL. Elevated WBC suggests infection or inflammation. Very high counts may need urgent investigation. Low WBC means reduced immunity. Platelet count is critical for blood clotting — normal is 150,000-400,000/uL. Low platelets are a key marker in dengue fever monitoring. At Klinik Muhibbah, an FBC is available — please call for current pricing and is part of our basic screening package. If your doctor orders an FBC, they are getting a comprehensive overview of your blood health.

Lipid Profile: Your Heart Health Numbers
The lipid profile measures fats in your blood that affect cardiovascular health. Total Cholesterol should be below 5.2 mmol/L. LDL Cholesterol (the "bad" cholesterol) should be below 3.4 mmol/L for most people, or below 2.6 mmol/L if you have diabetes or heart disease. LDL causes plaque buildup in arteries. HDL Cholesterol (the "good" cholesterol) should be above 1.0 mmol/L for men, 1.2 mmol/L for women. HDL actually removes cholesterol from arteries. Triglycerides should be below 1.7 mmol/L. High triglycerides are associated with fatty liver and metabolic syndrome. The Total Cholesterol/HDL ratio is also important — below 4.5 is ideal. Diet, exercise, genetics, and medications all influence these numbers. If your lipid profile is abnormal, our doctors will discuss whether lifestyle changes alone are sufficient or if statin medication is needed. A lipid profile at Klinik Muhibbah is available — please call for current pricing and requires 10-12 hours fasting.
3
Blood Sugar: Detecting Diabetes
Two key tests assess diabetes. Fasting Blood Sugar (FBS) measures glucose after 10-12 hours of fasting. Normal is below 5.6 mmol/L. Pre-diabetes is 5.6-6.9 mmol/L. Diabetes is diagnosed at 7.0 mmol/L or above. However, FBS only captures one moment in time. HbA1c (glycated haemoglobin) is the gold standard — it measures your average blood sugar over the past 2-3 months by looking at how much glucose is attached to your red blood cells. Normal HbA1c is below 5.7%. Pre-diabetes is 5.7-6.4%. Diabetes is diagnosed at 6.5% or above. For existing diabetics, the treatment target is usually below 7.0%, though your doctor may set individual targets. HbA1c does not require fasting. At Klinik Muhibbah, HbA1c is available — please call for current pricing. If you are diabetic, this test every 3 months is essential for monitoring whether your treatment is working effectively.
4
Liver and Kidney Function: Vital Organ Health
Liver Function Tests (LFT) measure enzymes released when liver cells are damaged. ALT and AST are the most important — normal is below 40 U/L. Mildly elevated levels (40-100) are common with fatty liver, medications, or recent alcohol. Moderately to highly elevated levels need further investigation for hepatitis, medication toxicity, or other liver diseases. ALP and GGT provide additional information about bile duct function. Albumin reflects the liver's protein-producing ability. Bilirubin causes jaundice when elevated. An LFT at Klinik Muhibbah is available — please call for current pricing. Kidney Function Tests (Renal Profile) measure waste product clearance. Creatinine is the key marker — normal varies by age and muscle mass but is generally below 110 umol/L. eGFR (estimated glomerular filtration rate) is calculated from creatinine and indicates what percentage of kidney function you have — above 90 is normal, below 60 indicates chronic kidney disease. Urea is another waste marker. A renal profile is available — please call for current pricing at our clinic.

What to Do With Abnormal Results
Receiving abnormal blood test results can be anxiety-inducing, but context matters. Many mildly abnormal results correct themselves — a slightly elevated white blood cell count during a cold, or mildly raised liver enzymes after a night of drinking. Your doctor interprets results in the context of your symptoms, medications, and overall health picture. If results are abnormal, ask your doctor these questions: Is this mildly or significantly abnormal? Could it be caused by something temporary? Do I need to repeat the test? Do I need additional tests? What changes should I make? Do I need medication? When should I retest? At Klinik Muhibbah, our doctors take time to explain your results in plain language, show you what is normal and abnormal, and create an action plan. For ongoing monitoring (diabetes, cholesterol, kidney disease), we keep your historical results so we can track trends over time. Remember, blood tests are a snapshot — trends over multiple tests are more meaningful than any single result.

Frequently Asked Questions
What does it mean if my FBC is abnormal?▼
It depends on which component is abnormal. Low haemoglobin means anaemia. High white cells suggest infection. Low platelets need monitoring. Your doctor will interpret the specific pattern and recommend next steps.
Should I worry about slightly high cholesterol?▼
Mildly elevated cholesterol can often be managed with diet and exercise. Your overall cardiovascular risk (age, diabetes, smoking, blood pressure) determines whether medication is needed. Discuss with your doctor.
How often should blood tests be repeated?▼
Annual screening for healthy adults over 35. Every 3 months for chronic conditions like diabetes. Your doctor will recommend the right frequency based on your results and conditions.
