The usefulness of testosterone administration in identifying false-positive elevation of serum human chorionic gonadotropin in patients with germ cell tumor
2018
Objective
The pituitary production of human chorionic gonadotropin (hCG) can cause false-positive results during or after germ cell tumor (GCT) treatment. Because hypogonadism leads to pituitary hCG production, testosterone administration test (TAT) has been recommended for pituitary hCG diagnosis. However, little is known about its efficacy for the discrimination of pituitary hCG as detected by currently used hCG assays in treatment of GCT. We conducted a retrospective multicenter study to determine the usefulness of TAT.
