Determination of testosterone using the HealthID PSD microsampling device
Determination of testosterone by liquid Chromatography–Tandem mass spectrometry in dried plasma obtained from capillary blood using the HealthID PSD microsampling device.
Monitoring testosterone (T) levels is essential in various clinical contexts, but traditional venous sampling is invasive and limits access.
This study describes the development and validation of a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantify T in dried plasma spot (DPS) samples obtained from capillary blood using the HealthID PSD microsampling device.
