Note: If total testosterone levels are greater than the cutoff for this test (>1500), results for free testosterone and/or percent free testosterone may not be provided. If total testosterone results are expected to be >1500 it is best that the LC/MS-MS version of this test be ordered.
If using a testosterone cream please be sure you have not rubbed any into the antecubital area of your arm for the last 24 hours as it can give elevated results. This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H or coenzyme R). It is recommended to stop biotin consumption at least 72 hours prior to the collection of specimen.
