Technical information, troubleshooting and answers to common questions related to diagnostic kits.
Rapid Test kits Human
Why does the control line not appear?
+
The absence of a control line indicates an invalid test. Possible reasons include insufficient sample volume, incorrect procedure, damaged kit or improper storage conditions.
Does the result reading time affect the test result?
+
Yes. The result must be interpreted within the time range specified in the product instructions. Reading the result earlier or later than the recommended time may lead to incorrect interpretation.
Why is the test line very faint?
+
A faint test line may be caused by a low concentration of the target analyte in the sample. The result should be interpreted according to the specific product instructions.
Molecular detection kits
Why does the PCR internal control fail to amplify?
+
Failure of internal control amplification may be caused by improper DNA/RNA extraction, the presence of PCR inhibitors, errors in reaction preparation, or improper storage conditions of reagents.
What factors can reduce the PCR signal?
+
Poor sample quality, low target concentration, extraction problems, reaction preparation errors, or inappropriate Real-Time PCR instrument settings may reduce the PCR signal.
Rapid Test kit Veterinary
Does the sample type affect veterinary test results?
+
Yes. Sample quality, collection time, transportation method, and storage conditions directly affect the accuracy of test results.
