• Q. The control line is barely visible. Is this a valid test?

  If the control line is barely visible, it may indicate that the test result is not reliable. In such cases, the message [Control Line Not Detected] will be displayed, and no test result will be shown. However, even if the control line is barely visible to the naked eye, the device may still produce valid test results. If this occurs, interpret the results according to the indicated test result, as a minimal amount of valid testing may have occurred. If the test results are not normal, the main causes may be:

  • Incomplete Separation of Serum:

    1. Ensure that the 1ml SST tube is thoroughly mixed with blood and allowed to stand for at least 15 minutes.

    2. If coagulation factors in the blood are not completely separated, the diluent may not flow smoothly on the pad. Verify the viscosity of the serum.

    3. Even if the serum color differs from normal (e.g., hemolysis - dark yellow, hyperlipidemia - white, normal serum - light beige), it does not significantly affect the test results.

  • Incorrect Diluent Volume:

    1. Confirm that the pipette is functioning properly.

    2. Inconsistent sample/diluent volumes during pipetting can affect the test results.

    3. Since the sample size for the test is small, wipe off any excess sample from the pipette exterior with lens paper before dispensing.

    4. Ensure that the tip of the pipette is fully submerged in the diluent below the bubbles before drawing the diluent.

  • Improper Kit Storage:

    1. Kits past their expiration date may not show proper coloration.

    2. Prolonged exposure to high temperatures may cause protein denaturation, preventing the kit from displaying correct coloration.

    3. When stored refrigerated, let the kit stand at room temperature for more than 30 minutes before use.

• Q. Why do I get different results when retesting the same sample?

  In theory, if you conduct a retest using the same sample, you should obtain results within a certain margin of error. However, the results can vary due to the following reasons:

  • Improper Storage of Serum: If the sample is not stored properly, such as leaving the serum at room temperature for an extended period, protein denaturation can occur, affecting the results. For retesting, use samples stored at room temperature within 1-2 hours, and for tests conducted after one day or more, it is recommended to store the samples in a refrigerator or freezer.

  • Inconsistent Sample/Diluent Volumes: The results can be affected if there is too little or too much sample/diluent during pipetting. Ensure that the pipette is functioning correctly.

  • Improper Kit Storage or Defective Kit: If the kit storage conditions were not appropriate or the kit is defective, the results can vary. If this issue persists, please contact customer service.

• Q. The coloration on the kit does not match the result values. Can I trust the results?

  All AniScan test kits undergo a scanning process with the AniScanner device. The scanned coloration data is then adjusted and analyzed on the web server before the final results are reported. Generally, the numerical values in the result report align with the degree of coloration on the kit. However, even if some values do not match exactly, the test has been conducted correctly, and the results reported through the website can be trusted.
