A positive result on an hCG (Human Chorionic Gonadotropin) cassette indicates the presence of the hCG hormone in the urine sample, which typically signifies pregnancy. The interpretation of a positive result on an hCG cassette depends on the appearance of lines or symbols in the test window. Here's how to interpret a positive result: Test Line and Control Line Visible: In most hCG cassettes, a positive result is indicated by the appearance of two lines: the test line and the control line. The test line appears if hCG is present in the urine sample, while the control line serves as a procedural control, indicating that the test is working properly. If both lines are visible, even if the test line is faint, it is considered a positive result. Symbolic Indication: Some hCG cassettes may use symbols, such as a plus sign (+) or the word "pregnant," to indicate a positive result. In this case, the appearance of the symbol in the test window indicates a positive result. Timing and Intensity: The timing and intensity of the lines or symbols may vary depending on the sensitivity of the test and the concentration of hCG in the urine sample. A positive result can occur within the specified development time mentioned in the test instructions. It's important to note that even a faint line in the test window should be considered a positive result, as it indicates the presence of hCG in the urine. However, if there is any doubt about the interpretation of the result, or if the result is unclear, it's advisable to repeat the test with a new cassette or consult with a healthcare professional for further evaluation and confirmation. |
