  Purpose

RATIONALE: Finding a better way to measure levels of sex hormones in the blood may help doctors monitor cancer in future patients.

PURPOSE: This study is looking at different ways of measuring sex hormones in blood samples from healthy participants to see which one is the best.

Study Type: Observational
Official Title: Reproducibility of Serum Sex Steroid Measurement: A Proof of Performance Study

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Reproducibility of sex steroid assays including gas chromatography-mass spectrometry (GC-MS) and liquid chromatography (LC) -MS-MS [ Designated as safety issue: No ]
  • Compare results of GC-MS and LC-MS-MS with those of radioimmunoassay [ Designated as safety issue: No ]

Estimated Enrollment: 60
Detailed Description:

OBJECTIVES:

  • Evaluate reproducibility of sex steroid assays, including testosterone, dihydrotestosterone, androstenedione, estrone, estradiol, androstenediol, and dehydroepiandrosterone (DHEA) by gas chromatography-mass spectrometry (GC-MS) and androstenediol glucuronide, androsterone glucuronide, DHEA sulfate, and estrone sulfate by liquid chromatography (LC)-MS-MS.
  • Evaluate the reproducibility of the measurement of these steroids and metabolites by radioimmunoassay (RIA).
  • Compare the assay results of GC-MS and LC-MS-MS to those of RIA.

OUTLINE: Participants undergo blood collection for laboratory analysis. Samples are analyzed by gas chromatography-mass spectrometry (MS), liquid chromatography-MS-MS, and radioimmunoassay to assess the reproducibility of these assays for measuring sex steroids.
