Your Health. A Healthier Tomorrow.
Blood tests can provide useful information about blood sugar, cholesterol, blood cells and organ function. Learn what common tests measure, why they may be recommended and how to choose a suitable health screening package in Johor Bahru.
Explore Health Screening PackagesDepending on the package and your health needs, a medical check-up may include a full blood count (FBC), blood glucose or HbA1c, a lipid profile, and selected liver or kidney function tests. Other tests, such as thyroid function, ferritin or vitamin D, may be recommended in certain situations. There is no single blood test panel that is suitable for everyone.
You may feel well and have no obvious symptoms, but certain health changes cannot be identified by how you feel alone. Blood tests can provide information about selected aspects of your health and help healthcare professionals assess possible risk factors.
For example, a blood glucose test measures sugar in your blood, while a lipid profile measures different types of blood fats. A full blood count examines blood cells, and selected biochemical tests help assess liver or kidney function.
These tests answer different questions. Choosing a health screening package is therefore not simply about selecting the package with the most tests. The goal is to identify tests that are appropriate for your age, medical history, family history and individual risk factors.
Unnecessary testing can lead to confusing or incidental findings and further investigations that may not be needed. Discuss the purpose, benefits and limitations of recommended tests with a healthcare professional.
The following tests assess different parts of your health. Availability varies between screening packages, and the tests listed here are not a recommendation that everyone should have all eight.
A full blood count measures components of your blood, including red blood cells, white blood cells, haemoglobin and platelets. It may help identify findings that warrant assessment for conditions such as anaemia or certain blood disorders.
May be relevant for: Assessing blood cell counts as part of an appropriate health evaluation.
A blood glucose test measures the amount of sugar in your blood at a particular time. A fasting blood glucose test is taken after a specified fasting period.
May be relevant for: Assessing blood sugar and screening for diabetes when indicated.
HbA1c reflects average blood glucose over approximately the previous two to three months. Unlike a fasting glucose test, it does not measure only the blood sugar level at one moment.
May be relevant for: Diabetes screening or monitoring when appropriate.
A lipid profile commonly measures total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. Results help assess cardiovascular risk alongside factors such as blood pressure, smoking and medical history.
May be relevant for: Assessing cholesterol levels and heart health risk factors.
These blood tests measure selected enzymes, proteins or other markers related to the liver. Depending on the tests ordered, results may help identify changes that need further evaluation.
May be relevant for: Assessing liver-related findings based on symptoms, risk factors or a screening plan.
Blood tests such as creatinine can help assess kidney function. Estimated glomerular filtration rate (eGFR) is commonly calculated using creatinine and other relevant information. Urine tests may also be needed to assess kidney health.
May be relevant for: People whose medical history or risk factors warrant kidney assessment.
Thyroid tests, such as thyroid-stimulating hormone (TSH), help assess thyroid function. Additional thyroid hormone tests may be requested depending on the initial results and clinical circumstances.
May be relevant for: People with suggestive symptoms, specific risk factors or a clinical reason for testing.
Ferritin is a marker used to assess the body's iron stores, while a vitamin D blood test usually measures 25-hydroxyvitamin D. These tests may be useful in selected circumstances, but they are not necessary for every routine check-up.
May be relevant for: People with specific symptoms, risk factors or clinical indications.
Note: The tests described above are examples of common blood tests, not confirmation that all are offered in every Southern Health Centre screening package. Check the actual package inclusions before booking.
Use this table as a quick reference when comparing the blood tests listed in a medical check-up package.
| Blood Test | What It Measures | Main Purpose |
|---|---|---|
| Full Blood Count (FBC) | Blood cells and haemoglobin | Assess blood cell counts |
| Blood Glucose | Blood sugar at the time of testing | Assess blood glucose |
| HbA1c | Glycated haemoglobin | Estimate average blood glucose over about 2–3 months |
| Lipid Profile | Cholesterol and triglycerides | Assess cardiovascular risk factors |
| Liver Function Tests | Selected liver-related markers | Assess liver-related findings |
| Kidney Function Tests | Markers such as creatinine and calculated eGFR | Assess kidney function |
| Thyroid Function Tests | TSH and, when indicated, thyroid hormones | Assess thyroid function |
| Ferritin | A marker of iron stores | Investigate iron deficiency when indicated |
| Vitamin D | Usually 25-hydroxyvitamin D | Assess vitamin D status when appropriate |
No single test provides a complete picture of your health. Results should be interpreted alongside your symptoms, medical history and other relevant findings.
Not necessarily. Some additional tests are useful when there is a specific reason to investigate a concern, but ordering more tests does not automatically make a check-up more effective.
A healthcare professional may consider factors such as:
For example, ferritin may be considered when investigating suspected iron deficiency, while thyroid function tests may be appropriate for certain symptoms or risk factors. Vitamin D testing may be considered when there is a clinical reason to assess vitamin D status.
Before selecting a health screening package, ask what each test is intended to assess, whether it is suitable for you and how abnormal results will be followed up.
If you are comparing medical check-up packages in Johor Bahru, look beyond the number of tests included. Consider whether the package addresses your health needs and whether the process for reviewing your results is clear.
You can compare the available health screening packages at Southern Health Centre before deciding which option to discuss with the healthcare team.
Preparation depends on the specific tests ordered. Some blood tests require fasting, while others can be performed without fasting.
If you are unsure whether to fast, contact the screening centre before your appointment rather than assuming that all blood tests require fasting.

Depending on your circumstances, a clinician may consider tests such as a full blood count, blood glucose or HbA1c, lipid profile, or selected liver and kidney function tests. Not everyone needs every test.
Depending on the package, blood tests may include a full blood count, blood glucose, cholesterol measurements and selected markers of liver or kidney function. Some packages may offer additional tests. Always check the actual test list because package inclusions vary.
A full blood count (FBC) measures blood components such as red blood cells, white blood cells, haemoglobin and platelets. HbA1c measures glycated haemoglobin and reflects average blood glucose over roughly two to three months. They assess different aspects of health.
No. Blood tests provide information about specific markers or body functions, but they cannot detect every disease. Some conditions require a physical examination, imaging, urine testing or other investigations. A normal blood test does not rule out every condition.
It depends on the tests included. Some tests require fasting, while others do not. Follow the instructions from your clinic and ask the healthcare team if you are uncertain.
Not necessarily. The number of tests alone does not determine the quality of a health screening. Choose based on your health needs, relevant risk factors, the tests included and the process for interpreting and following up on results.
You can review the available options on the Southern Health Centre health screening page . Confirm the available tests, package inclusions, preparation requirements and appointment arrangements directly with the centre.
An abnormal result does not always mean that you have a medical condition. Your healthcare professional can interpret it in context and advise whether repeat testing, further investigations or treatment is needed. Do not diagnose yourself based on a single result.
