Trial Outcomes & Findings for Phlebotomy Study of Testosterone Undecanoate (NCT NCT02670343)

NCT ID: NCT02670343

Last Updated: 2018-03-09

Results Overview

The measured outcome presented is the difference as a percent of mean of T results when comparing T Concentrations measured in three different types of NaF containing collection tubes (NaF+EDTA, NaF+Oxalate and NaF) to T measured in blood collected in plain tubes. The % of Mean Difference in T concentration for each tube type was obtained by taking the average at each time point a T concentration was obtained, and calculating the mean difference between the test ((NaF+EDTA, NaF+Oxalate and NaF) tubes and the control (plain) tube. The concentration of total T will be determined in the serum/plasma samples of all subjects using validated LC/MS/MS methods at the Endocrine and Metabolic Research Lab.
