Weight Loss Blood Test

Attend your appointment and one of our experienced nurses or phlebotomists will collect your blood sample. If your test also includes another sample, such as urine or stool, we will provide the necessary collection kit and clear instructions.

Results are typically available within Same day. Some individual markers may take longer if they require specialist laboratory processing. We will normally wait until the full profile is complete before issuing your reviewed results.

Fasting is not essential for most cholesterol tests. LDL and HDL cholesterol change very little after eating, although triglycerides can be more affected. You may therefore choose to fast for 8–12 hours for the clearest triglyceride result, but for most people either approach is acceptable. Plain water is fine.

Where practical, avoid strenuous exercise for 24 hours beforehand. Heavy exercise can temporarily affect creatine kinase (CK), AST and some other results.
