Intended Use:

Mycoplasma pneumoniae Antigen Rapid Test Cassette is a rapid chromatographic immunoassay for the qualitative detection of Mycoplasma pneumoniae(M. pneumoniae) antigens in human throat swabs. It is intended to aid in the rapid differential diagnosis of Mycoplasma pneumoniae infections.

TEST PRINCIPLE

The Mycoplasma pneumoniae Antigen Rapid Test Cassette a qualitative, lateral flow immunoassay for the detection of M. pneumoniae antigen in a throat swab. In this test, antibody specific to M. pneumoniae antigen is coated on the test line region of the test. During testing, the extracted throat swab specimen reacts with an antibody to M. pneumoniae that is coated onto particles. The mixture migrates up the membrane to react with the antibody to M. pneumoniae on the membrane and generate a color line in the test line region. The presence of this color line in the test line region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

TEST PROCEDURE

Allow the test, specimen, extraction buffer to equilibrate to room temperature (15-30°C) prior to testing.

Remove the test cassette from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the assay is performed immediately after opening the foil pouch.

1. Place the Extraction Tube in the workstation. Hold the extraction reagent bottle upside down vertically. Squeeze the bottle and let the solution drop into the extraction tube freely without touching the edge of the tube. Add 10 drops of solution (Approx. 400μl) to the Extraction Tube. See illustration 1.
2. Place the swab specimen in the Extraction Tube. Rotate the swab for approximately 10 seconds while pressing the head against the inside of the tube to release the antigen in the swab. See illustration 2.
3. Remove the swab while squeezing the swab head against the inside of the Extraction Tube as you remove it to expel as much liquid as possible from the swab. Discard the swab in accordance with your biohazard waste disposal protocol. See illustration 3.
4. Fit the dropper tip on top of the extraction tube. Place the test cassette on a clean and level surface. See illustration 4
5. Add three drops of the solution (approx.120μl) to the sample well and then start the timer. Read the result at 15 minutes. Do not interpret the result after 20 minutes.

Caution: The above interpreting time is based on room temperature range of 15-30℃. If your room temperature is significantly lower than 15℃, then the interpreting time should be properly increased to 30 minutes.

INTERPRETATION OF RESULTS

Positive:

Two red lines are visible in the result window. The intensity of the test line may be

weaker or darker than that of the control line. This still means a positive result.

Negative:

The control line appears in the result window, but the test line is not visible.

Invalid:

If the control line does not appear in the result window, the test results are INVALID regardless of the presence or absence of the line in the test region.

PERFORMANCE CHARACTERS:

Sensitivity, Specificity and Accuracy

The Mycoplasma pneumoniae Antigen Rapid Test Cassette (Throat Swab) has been evaluated with specimens obtained from the patients. PCR is used as the reference method for the Mycoplasma pneumoniae Antigen Rapid Test Cassette (Throat Swab). Specimens were considered positive if PCR indicated a positive result. Specimens were considered negative if PCR indicated a negative result.

Relative sensitivity: 94.3% (95%CI*: 80.8%~99.3%);

Relative specificity: 98.7% (95%CI*: 99.6%~100.0%);

Accuracy: 98.2% (95%CI*: 95.7%~99.4%). *Confidence Intervals

NOTE: Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure. Review the procedure and repeat the test with a new device. If problem persists, please contact your local distributor.
