      General usage of YHLO rapid test kit<\/h2>\r\n

      The following is a common procedure for rapid antigen testing. Since different YHLO models may have different specifications, please refer to the instructions inside the box for the actual number of drops and waiting time.<\/p>\r\n

        \r\n
      1. Open the packaging and remove the test card, sampling stick, sample buffer, and other accessories.<\/li>\r\n
      2. As instructed in the instructions, use the sampling stick to collect nasal or other designated samples at the specified location.<\/li>\r\n
      3. Place the sampling swab into the sample buffer solution and stir and squeeze thoroughly as instructed in the instructions to mix the sample with the solution.<\/li>\r\n
      4. Add the specified number of sample solutions to the sample wells of the test card; do not increase or decrease the number of drops yourself.<\/li>\r\n
      5. Read the results at the time specified in the instruction manual. Reading too early or too late may result in incorrect results.<\/li>\r\n
      6. After completion, carefully wrap and discard the used components, and clean your hands again.<\/li>\r\n<\/ol>\r\n

        Only C line<\/td>\r\nThis generally indicates that the test was valid and the target antigen was not detected.<\/td>\r\nIf you have symptoms or have had high-risk exposure, a single negative test cannot completely rule out infection. You should follow the latest official guidelines and repeat the test or seek medical attention as needed.<\/td>\r\n<\/tr>\r\n
        The C line and T line appear simultaneously<\/td>\r\nThis generally indicates that the target antigen may have been detected. Even if the T line is light in color, it should be treated according to the positive guidelines in the instruction manual.<\/td>\r\nDo not treat the result as a normal negative result for now; follow up according to the latest official guidelines and medical staff advice.<\/td>\r\n<\/tr>\r\n
        No C line<\/td>\r\nThe test is invalid; this test card cannot be used to determine whether the result is negative or positive.<\/td>\r\nRetest using the new test kit and check that the operation was performed according to the instructions.<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/figure>\r\n

        Note: Some all-in-one rapid tests may have additional A, B, or other test lines, and the interpretation methods may differ. Do not directly apply the interpretation methods of other brands or all-in-one products to the YHLO single COVID-19 antigen test.<\/p>\r\n<\/blockquote>\r\n

        What should I do if my YHLO rapid test is positive, negative, or invalid?<\/h2>\r\n

        Positive<\/h3>\r\n

        A positive result indicates that SARS-CoV-2 antigen may have been detected in the sample, but a rapid test cannot replace a doctor's diagnosis. Please follow the latest official guidelines and advice from healthcare professionals in Hong Kong; if you experience difficulty breathing, persistent high fever, confusion, or other severe discomfort, seek medical attention as soon as possible.<\/p>\r\n

        Negative<\/h3>\r\n

        A negative result does not necessarily mean there is no infection, especially in the early stages of infection, when symptoms are just beginning, or when the sample size is insufficient, false negatives may occur. If you have symptoms or have been exposed to risk factors, you should monitor your health and repeat the test in the short term according to the latest official guidelines or seek medical advice.<\/p>\r\n

        invalid<\/h3>\r\n

        If no C line appears, this test is unusable. Please retest with a new test kit. Do not assume a negative result based solely on the absence of color or the presence of only a T line.<\/p>\r\n

        The Hong Kong Department of Health's rapid antigen test database once listed YHLO GLINE-2019-nCoV Ag, but when checking, you should also verify the product model, packaging, supplier, and current valid information, and do not judge the product status based solely on the brand name.<\/p>\r\n
