Which is the appropriate time for collection of blood for estimating most of its biochemistry constituents?

Correct option is A

. Ans (a)
Sol. Explanation:
· Fasting blood samples are typically preferred for the accurate estimation of most biochemical constituents like blood glucose, lipid profile (cholesterol, triglycerides), liver enzymes, and kidney function tests. This is because eating can temporarily alter the levels of these substances in the blood.
· Post-prandial (after meal) samples are used specifically to measure post-meal blood glucose levels, but are not generally used for routine biochemical testing.
· Immediately after meals and after giving a stimulant are not the recommended times for most routine biochemistry tests, as the results could be affected by recent food intake or stimulation.
