Which of following tests in used to detect semen?
**Core Concept**
The detection of semen in forensic medicine is crucial in cases of alleged sexual assault. Semen contains enzymes like acid phosphatase and fructose, which can be used as markers for its presence.
**Why the Correct Answer is Right**
The test used to detect semen is the **Acid Phosphatase (ACP) Test**. This test relies on the presence of acid phosphatase, an enzyme found in high concentrations in semen. Acid phosphatase catalyzes the conversion of various substrates to yield a colored product, which can be detected using a chemical reagent. This test is commonly used in forensic medicine to confirm the presence of semen on a victim's clothing or body.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to semen detection.
**Option B:** While other tests like the Semen Specific Protein-A (SSP-A) test exist, the Acid Phosphatase Test is more commonly used and widely accepted in forensic medicine.
**Option C:** This option is not a recognized test for semen detection.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the presence of acid phosphatase does not necessarily confirm sexual assault, as the enzyme can also be present in other bodily fluids or tissues. However, its presence can be a useful indicator in conjunction with other evidence.
**Correct Answer:** A. Acid Phosphatase Test
