Prostatic Specific Antigen ( PSA)

The PSA Rapid Test Cassette (Whole Blood /Serum /Plasma) is a semi-quantitative,
membrane based immunoassay for the detection of PSA in whole blood, serum or plasma.
The membrane is pre-coated with PSA antibodies on the test line region. During testing, the
specimen reacts with the particle coated with anti-PSA antibody. The mixture migrates upward
on the membrane chromatographically by capillary action to react with anti-PSA antibodies on
the membrane and generate a colored line. A test line (T) intensity weaker than the reference
line (R) indicates that the PSA level in the specimen is between 3-10ng/ml. A test line (T)
intensity equal or close to the reference line (R) indicates that the PSA level in the specimen is
approximately 10ng/ml. A test line (T) intensity stronger than the reference line (R) indicates
that the PSA level in the specimen is above 10ng/ml. To serve as a procedural control, a
colored line will always appear in the control line region (C) indicating that proper volume of
specimen has been added and membrane wicking has occurred.
