Question

Percentage of foetal protein present in human adult is

• A. 1%
• B. 2%
• C. 3%
• D. None of the above.

Answer 1

The correct option is A 1%

AFP is the most abundant plasma protein found in the human fetus. Maternal plasma levels peak near the end of the first trimester, and begin decreasing prenatally at that time, then decrease rapidly after birth. Normal adult levels contain 1% which are usually achieved by the age of 8 to 12 months.

So, the correct answer is '1%.'
