Some PRAMITA friends may often receive instructions to fast before undergoing laboratory tests. But is it true that all blood tests must be done when the body is in a fasted state?

Why Do Some Tests Require Fasting?
Fasting before laboratory tests is intended to ensure the results are more accurate and not influenced by previously consumed food or drink. Several blood components can change significantly after eating, such as blood sugar and fat levels. If not fasting, the results might show higher levels than the actual condition. This could lead to a misdiagnosis.

For example, fasting blood glucose tests require no food intake for at least 8 hours. The purpose is to measure blood sugar at its baseline level, without food influence. Likewise, triglyceride tests require fasting to avoid high levels due to fatty foods.

Blood Tests That Do Not Require Fasting
Not all blood tests require fasting. Many remain accurate even after eating, such as:

Liver function tests (SGOT, SGPT)

Kidney function tests (urea, creatinine)

Complete blood count (hemoglobin, white cells, platelets)

Hormonal tests like TSH, T3, T4

Infection tests (CRP, procalcitonin)

Conclusion
Not all blood tests require PRAMITA friends to fast. While tests like fasting glucose and complete lipid profile do require fasting, many others are still valid post-meal. For best results, consult medical staff or lab professionals to confirm if fasting is needed. Correct information helps prevent diagnostic errors and smoothens the lab process.
