b) 1-2 Weeks; 3-4 Weeks
c) 2-3 Weeks; 5-6 Weeks
d) 3-4 Days; 10-14 Days

Answer 1

Serum bHCG can be detected as soon as 3-4 days after conception, while urine bHCG can typically be detected between 10-14 days after conception.

Step-by-step explanation:

Human beta chorionic gonadotropin (bHCG), which is a marker for pregnancy, can be detected relatively early after conception. The presence of bHCG is what is tested for in both urine and serum pregnancy tests. After conception, the newly formed zygote will begin to secrete this hormone, which is an indication that implantation of the embryo into the uterine wall is underway and that pregnancy has begun.

The correct answer to the question of how soon after conception serum bHCG can be detected is d) 3-4 Days; when it comes to detection in urine, the correct timeframe is 10-14 Days. This means that for a blood-based serum test, bHCG can be detected just a few days after conception has taken place, while urine-based tests typically require a slightly longer period before they will return a positive result.
