Self-test for the determination of the Prostate-Specific Antigen (PSA) in whole blood samples
PROSTATE-SPECIFIC ANTIGEN (PSA)
Prostate Specific Antigen (PSA) is a protein produced by the cells of the epithelium of the prostate gland with the task of thinning the ejaculate, allowing better sperm motility.
This protein also plays a role in the dissolution of cervical mucus, facilitating the entry of sperm into the uterus. Normally, PSA is present in men’s blood with a healthy prostate in small quantities. In the presence of prostate diseases (such as prostatitis, benign prostatic hyperplasia and cancer) PSA levels in blood increase. PSA levels undergo a physiological increase with advancing age or after prostate surgery and as a consequence of specific diagnostic tests.
WHO IS THIS TEST FOR?
PROSTATE PSA TEST is indicated for men with urinary symptoms or as a periodic screening over 45 years of age.
Among the most common symptoms related to a possible prostatic pathology there are: difficulty in urination, pain and increased frequency. Periodically checking the PSA level in the blood is useful for verifying the health of the prostate: in the event of possible prostate cancer, early diagnosis and proper prevention can save lives.
PROSTATE PSA TEST is an immunochromatographic device that detects PSA values above the cut-off of 4 ng/mL.
1 test cassette
1 vial with dropper containing the diluent
2 sterile lancets
1 pipette for blood sampling
1 cleanser gauze
instructions for use
Draw a blood sample by using the sterile lancet provided;
Collect the sample indicated with the black line by using the capillary pipette provided;
Deposit the collected specimen into the sample well (S) indicated on the test cassette;
Add 2 drops of the diluent and wait 5 minutes before reading the result.
the PSA value obtained is within the norm.
the PSA value found is higher than the normal threshold, it is necessary to consult a specialist.

The test has been carried out correctly when the instructions for use are followed. It includes the reading time and the interpretation of the results shown at the "RESULTS INTERPRETATION" section of the instructions for use.
A colored line will appear at the control region (C) on the test device, showing that the test performed correctly. The absence of the colored line suggests to repeat the test with a new device and a new sample.
