Special Info
Prostatic secretions: Multiple samples are cultured. If one specimen grows far more bacteria than others, the infection is localized to the urethra, bladder, or prostate. VB1 (voided bladder 1) - 1st 10cc of urine represents urethra, VB2 - midstream urine represents bladder EPS (expressed prostatic fluid) - Prostate massaged; represents prostate and VB3 - also represents prostate.
Clinical Info
To transfer urine into C&S preservative tube: Submerge the tip of transfer straw into urine specimen. Push the gray top C&S preservative tube into the transfer straw. Hold in position until flow stops. It must be filled to the minimum fill line on the tube (3 ml). Remove tube leaving transfer straw in urine specimen container. Shake tube vigorously to mix sample. If both a UA (red/yellow) and C&S tube (gray top) are being collected, transfer urine to C&S tube first. Urine specimens are processed based on whether the specimen was collected with an invasive (straight catheter, suprapubic aspirate, cystoscopy) or noninvasive (midstream clean catch, indwelling catheter, stoma) method. A low colony count is performed on urine specimens collected via invasive methods. Normal flora from the urethra, vagina and perineum often contaminate urine specimens. Quantitation of bacteria helps to distinguish contaminated specimens from those representing infection. The most common uropathogens are normal intestinal flora organisms such as Escherichia coli, Klebsiella spp. Enterobacter spp., Proteus spp. and Enterococcus spp. The level of work up is based on the specimen type, number of different organisms growing, and the quantity of potential uropathogens in relation to urogenital flora. If culture is positive, identification will be performed on clinically significant organisms at an additional charge. Identification CPT codes that may apply include: 87077, 87088, 87106, 87107, 87153. Antimicrobial susceptibilities are performed when indicated, and the following CPT codes may apply: 87181, 87184, 87185, 87186.
