The One Step PSA in whole Blood Test is a chromatographic immunoassay in-vitro diagnostic test for the qualitative detection of Prostate Specific Antigen (PSA) tumor markers in human whole blood specimen.PSA tumor marker tests are based on the principle of sandwich immunossay for determination of PSA in human whole blood specimen.Two monoclonal antibodies are employed to identify cancer PSA specifically.The prostate specific antigen(PSA) is the most commonly tested Tumor marker for the prostate gland discase diagnosis. PSA tumor marker is normally present in low levels in the blood of all adult men. In human blood, the normal concentration range of this biomarker is 0.0 to 4.0 ng/ml, which are variable among different human races (refer to the table at the end of this page). But when prostate specific antigen rise beyond the normal range, it can be taken as a signal of prostate gland cancer or other problems. That is why PSA becomes the subject of PSA in whole blood detection devices.

For whole blood, collect blood into a container without anticoagulant. If the specimen cannot be tested on the day of collection, store the whole blood specimen in a refrigerator. Bring the specimens to room temperature before testing.

Negative: Only one colored band appears on the control (C) region. No apparent band on the test (T) region. Positive: In adition to a pink colored control (C) band, a distinct pink colored band will also appear in the test (T) region. Please consult your physician to perform a much more detailed exam. Invalid: A total absence of color in both regions is an indication of procedure error and/or the test reagent has been deteriorated.
