Fasting sample requirements
In line with current guidance provided by the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM), for tests that require a fasting sample, we advise that the duration of the fast should be 12 hours.
This applies to the following tests:
- Fasting glucose
- Fasting lipids / triglycerides
- Homocysteine (free and total)
- Gut hormones / gastrin
- Calcitonin
- C-terminal telopeptide of type I collagen (CTx)
