Urine Three-glass Test

The urine Three-glass test is used to roughly determine the source of urinary hematuria and assist in identifying the site of urinary tract bleeding. In the three-glass test, patients leave urine in 3 test tubes, the first tube contains the washings from the anterior urethra, the second, material from the bladder, and the last, material from the posterior urethra, prostate, and seminal vesicles.

The microscopic examination of the three test samples will tell us which tube contains blood. It indicates where the bleeding possibly locates.
