Serum/plasma concentration of garlic-derived organosulfur compounds (e.g., diallyl sulfide, diallyl disulfide)

What This Test Measures

Garlic contains organosulfur compounds like diallyl sulfide and disulfide, which are metabolized in the body. This test quantifies their levels in your blood plasma or serum. These compounds are not typically measured for routine health monitoring but may be studied in research or specific clinical scenarios.

Why It Might Be Ordered

Your healthcare provider may order this test if there is a suspected exposure to garlic products, research involvement requires monitoring specific metabolites, or as part of a specialized study. It is not a standard diagnostic test for common health conditions.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in the arm. The blood is processed to separate plasma or serum, which is then analyzed for the presence of these organosulfur compounds. You may be asked to fast or avoid garlic-containing foods for a specified period before the test, depending on the protocol.

What to Expect Before the Test

Prepare for the blood draw as you would for any standard blood test. Avoid consuming garlic products for at least 24 hours before the test if instructed, as this can affect the test results. Wear comfortable clothing and bring any necessary identification or insurance information.
