What is the meaning of the C line in the antigen test?
Hi there! Thank you for reaching out. For the antigen testing, you may check our antigen testing instructions and you have the option to upload your antigen test result or get live results through this link: https://fastlabtech.com/antigen/
If the C line is present, the test result is Negative.
If both the C line and T line are present, the test result is Positive.
If the C line is absent, regardless whether the T line is present, the test result is considered as Invalid, and you should do another test with a new antigen test kit.
Should you have further questions, please do not hesitate to reach out. Have a great day!
