PSA, complex (cPSA) (Siemens: CLIA) (Serum (s), frozen)

Testcode:	E_CPSA
Specimens:	500 µl Serum (s), frozen
Preanalytics/Notes:	If the concentration of free PSA (fPSA) is desired, we offer direct measurement of fPSA as well as total PSA (tPSA) and calculate the fPSA/tPSA ratio, which has a comparable sensitivity and specificity for differentiating between prostate cancer and benign prostate enlargement as cPSA.
Method:	CLIA
Dimension:	ng/ml
Set-up:	Mon Tue Wed Thu Fri Sat Sun
Duration:	1 day
Indication/Significance:	PSA is used for early detection, therapy control and aftercare of prostate carcinoma. According to the guidelines of the German Society of Urology the investigation is indicated: with any man from the age of 45 years in men with micturition symptoms after exclusion of a urinary tract infection after surgical removal of a prostate carcinoma in the context of recurrent
Interpretation:	The biological half-life more… The biological half-life of the PSA is 2-3 days: high pre-operative values, therefore require weeks to normalize. Elevated: Prostate Ca benign prostate hypertrophy prostatitis In the extended gray range (3.2 - 8.3 ng / ml) the cPSA (from Siemens) was to be supplemented by the determination of the total PSA / t-PSA (from Siemens) and an interpretation aid was provided by quotient formation (see Preanalytic) from PSA and tPSA, the proportion of free PSA is calculated. close
