Brief Summary
This sponsor is an anti-doping laboratory tasked with testing athlete samples for prohibited substances by the World Anti-Doping Agency and other agencies. This study is intended to measure:
- 1.Urinary/serum hCG (human chorionic gonadotropin) and urinary biotin concentrations in both treatment groups before, during, and after hCG intervention using standard immunoassay methods
- 2.To monitor hCG in both treatment groups before and after diafiltration of urine samples prior to analysis
- 3.To compare urinary and serum detectability (detection window, sensitivity) of hCG abuse in the hCG-only group compared to the hCG + biotin group

Conditions
Outcome Measures
Primary Outcomes (2)
1. Urinary hCG and biotin concentrations
Urinary hCG concentration will be measured on different analytical platforms (Abbott, Roche, Siemens) that are dependent or not dependent on biotin-streptavidin chemistry for hCG measurement. Urinary biotin concentration will be measured using mass spectrometric techniques. Measured hCG concentrations, especially those during and after the dosing of Ovidrel, will be assessed in combination with the biotin concentration to understand the masking effect of biotin on urinary hCG measurement as it relates to anti-doping.
6 months
2. HPT-related hormone measurements in serum; biotin measurements in serum
hCG, LH (luteinizing hormone), FSH (follicle stimulating hormone), testosterone, SHBG (sex hormone binding globulin), and estradiol will be measured in serum before and after treatment with Ovidrel. Changes in each of these compounds will be compared to individual baseline values established prior to Ovidrel use to understand the drug effects. hCG and LH will be measured on analytical platforms known to be affected by biotin interference, and all analytes (including hCG and LH) will be measured on an analytical platform not affected by biotin interference.
6 months
Secondary Outcomes (3)
