Note: If total testosterone results are expected to be >1500 it is best to order a panel that includes the LC/MS-MS methodology for total Testosterone.
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. Some tests in this panel 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.
Estimated turnaround for results is 3 business days. If confirmation testing is required, the estimated time may be extended.
