- PSA Test detects a specific prostate antigen. This antigen is a glycoprotein produced by prostate cells. In the case of prostatic hypertrophy or prostate cancer, this antigen is present in the blood in elevated concentrations.
PSA is short for the English name "Prostate Specific Antigen" and represents a prostate-specific antigen. This antigen is produced by prostate gland cells (prostate) and mainly causes semen fluidisation. In healthy men, PSA gets into the bloodstream only in trace amounts. In men with morbidly changed prostate cells into the bloodstream, much more PSA antigens enter the bloodstream. Blood levels of PSA in the range of 0 ng / ml to 4 ng / ml are considered normal. Exceeding normal PSA values indicates prostate pathology (mild hypertrophy, inflammation, cancer, etc.) and should be an indication for further diagnosis in this direction. PSA testing should be performed every year in men over 50 years of age. PSA Test is a quick test,
COMPOSITION OF PACKAGING
The package contains the equipment needed to perform one test:
- 1 aluminum sealed envelope, containing: 1 test plate, 1 plastic pipette and 1 moisture absorber
- 1 container with a dropper containing 1 ml of diluent
- 1 sterile lancet for finger puncturing
- 1 test execution instructions
INSTRUCTIONS FOR USE
- The test is for in vitro diagnostic use only. This test is for external use only. DO NOT LEAVE.
- Please read the test manual thoroughly before carrying out the test. The test result is only reliable if the instruction is strictly followed. It is especially important to use the right amount of blood and diluent.
- Keep the PSA Test Pack at 4 - 30 ° C. Do not freeze.
- Do not use the test after the expiry date on the package. Do not use the test if the foil packaging is damaged.
- The test is only for single use.
- Keep out of the reach of children.
EXECUTION OF THE TEST
- Just before the test, wash your hands thoroughly with soap, rinse with water and dry.
- Tear the foil envelope along the incision and remove only the test plate and the plastic pipette. Discard the moisture absorbing agent.
- Take the lancet in hand and push in the orange element until you hear a characteristic click that indicates the lancet is active.
- Remove the orange element by "twisting" it to the left or right.
- Disinfect the tip of the middle finger or middle of the swab soaked with alcohol. Increase the blood supply of the pad by massaging the finger from the base of the finger to its tip.
- Apply the lancet to the disinfected finger pad so that it stays tight and press the spring release button.
- The blade automatically and securely retracts into the lancet casing.
- Slightly swipe your finger to get a higher drop of blood.
- Holding the pipette in a horizontal position, bring the tip to a drop of blood. Do not squeeze either the pipette or the pad. Under the influence of capillary forces, the blood will begin to flow into the pipette. Hold the dropper down to the droplet until the blood fills it to a black line. If necessary, swipe your finger again. Avoid air bubbles.
- Put the blood from the pipette into the round window on the test plate.
- Wait until the blood is completely absorbed and do not wait for 4-5 drops of diluent to enter the same window.
- Read the test result after 10 minutes. Do not take into account the result after more than 15 minutes.
INTERPRETATION OF THE RESULTS OF THE TEST
The intensity of the line streaks that appear in the result window does not affect the interpretation of the test results.
Two lines appear in the result window: T test band and control band C. The T band may be more pronounced than the C band. Positive test results indicate that blood levels of PSA are higher than normal and should be consulted with a physician.
result Only one line appears in the result window: control band C. Negative test results indicate that blood PSA levels are normal.
In the result window, no line appears or only T test line appears. In this case, there is no way to interpret the test result and repeat the test with a new blood sample and use a new test.
ANSWER TO THE MOST IMPORTANT QUESTIONS
- What is the performance of the PSA Test?
PSA Test detects a specific prostate antigen. This antigen is a glycoprotein produced by prostate cells. In the case of prostatic hypertrophy or prostate cancer, this antigen is present in the blood in elevated concentrations. The PSA concentration is 4 ng / ml for normal levels. PSA Test detects concentrations above 4 ng / ml. The PSA screening test covers men between 50 and 75 years of age.
- When should a PSA test be performed?
Test your PSA Test at any time of the day. However, in some cases, in order to avoid false positives, it is recommended to perform a delayed test:
- cycling, etc., after 24 hours,
- sperm injection, after 24 hours,
- Prostate massage, after 2 - 3 days,
- Transrectal ultrasound of the prostate, after 2 - 3 days,
- Cystoscopy of the lower urinary tract, after 1 week,
- Prostate resection through the urethra / biopsy, after 4 to 6 weeks
- Can the test result be incorrect? The test result is only reliable if the test is performed exactly as instructed. The test result may also be incorrect if the test plate becomes damp or when the amount of blood entering the circular window is insufficient. Pay attention to fill the pipette to a black line.
- How to interpret the test result if the line intensity is different?
The color and intensity of lines appearing in the result window are not relevant for the interpretation of the test result. The appearing bands should be visible and fully outlined.
- What is the line that appears under the letter C on the test plate?
The appearance of a colored band under the letter C indicates that the test is working properly and that the test was performed correctly.
