Abstract

The invention particularly relates to a detection card and a detection method for rapidly detecting early pregnancy and gestational weeks. The detection card comprises a detection strip, a pen cap anda pen-shaped card body, wherein the detection strip comprises a matrix support plate, absorbent paper, an analysis membrane, a gold-labeled combination pad and a sample pad, a gold-labeled mouse anti-HCG-alpha antibody is fixed on the gold-labeled combination pad, wherein the analysis film is coated with a detection line and a quality control line, the quality control line containing goat anti-mouse IgG antibodies is located on the right side of the detection line, the detection line comprises a detection line T1, a detection line T2 and a detection line T3 containing mouse anti-HCG-beta antibodies with different concentrations, and the HCG concentration range in urine is rapidly detected through a detection card. According to the detection card, the number of the detection lines is increased, different sensitivities are set, HCG hormones are rapidly detected, the concentration range of HCG in a urine sample is simply determined, the week of pregnancy is calculated according to the concentration range, and therefore a purpose of judging early pregnancy and week of pregnancy is achieved, an accurate week of pregnancy detection result is provided for women subjected to early pregnancy testing, and application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the field of in vitro diagnostic reagents, and in particular relates to a detection card and a detection method for rapidly detecting early pregnancy and gestational age. Background technique [0002] Gestational cycle refers to the period from conception to childbirth. Since it is difficult for every pregnant woman to accurately judge the time of conception, it is medically stipulated that the expected date of delivery is calculated from the first day of the last menstrual period. This calculation method is relatively imprecise. [0003] Human chorionic gonadotropin (HCG), a glycoprotein hormone secreted by placental trophoblast cells during pregnancy, consists of two different subunits, α and β. The examination of HCG is of great significance to the diagnosis of early pregnancy. The general early pregnancy detection test paper uses a double-antibody sandwich one-step method to detect HCG in urine, and colloidal gold is use...
