When the human chorionic gonadotropin in the body is greater than 25U/L, you can use early pregnancy test strips to detect it, choose morning urine to test more accurate, strictly in accordance with the instructions for the use of early pregnancy test strips or pregnancy tests. If the result of the test is 2 bars suggests pregnancy, if 1 bar suggests non-pregnancy, in the white area shows a 2 bar shades of change, related to the body of human chorionic gonadotropin, when the concentration is too low presents a shallow 1 bar, not obvious. When the concentration is high, the test is strongly positive and darker in color. Relatively speaking, blood tests for human chorionic gonadotropin are more accurate than test strips, because when the human chorionic gonadotropin in the body is too low, the reaction of the reagent is not particularly obvious, and it is easy to miss or misdiagnose the disease.
