The measurement of androgens

Area of Science:

• Endocrinology
• Clinical Chemistry
• Analytical Chemistry

Background:

• Androgens are crucial for clinical diagnostics, with testosterone being commonly measured.
• Routine labs may lack assays for less common androgens, necessitating specialized testing.
• Current automated systems for testosterone lack sensitivity for pediatric and normal female ranges.

Purpose of the Study:

• To provide simple, effective methods for androgen measurement in serum and saliva.
• To compare and contrast radioimmunoassay and tandem mass spectrometry for androgen analysis.
• To address the need for sensitive androgen assays in specific patient populations.

Main Methods:

• Radioimmunoassay (RIA) techniques for androgen quantification.
• Tandem mass spectrometry (MS/MS) as a modern analytical approach.
• Sample preparation and analysis protocols for serum and saliva matrices.

Main Results:

• Tandem mass spectrometry offers superior sensitivity and specificity compared to traditional radioimmunoassay.
• Radioimmunoassay remains a viable option for certain androgen assays where sensitivity is not paramount.
• The described methods enable accurate androgen measurement across various clinical scenarios.

Conclusions:

• Tandem mass spectrometry is increasingly replacing radioimmunoassay for sensitive androgen detection.
• Accurate measurement of androgens is vital for diagnosing and monitoring various endocrine disorders.
• The presented methods facilitate reliable androgen analysis in both routine and specialized laboratory settings.
