The invention discloses a
stomach cancer serological detection and identification kit and a method. The
stomach cancer serological detection and identification kit is prepared from a
cel-miR-39-5p fragment, a primer, an
exosome isolating
reagent, an
exosome miRNA (Micro Ribonucleic Acid) extracting
reagent, a reverse transcription
reagent and a real-time fluorescent quantitative PCR (
Polymerase Chain Reaction) reagent, wherein the primer comprises a
cel-miR-39-5p internal reference primer, an hsa-miR-375 primer, an hsa-miR-590-5p primer, an hsa-miR-19b-3p primer, an hsa-miR-100-5p primer and an hsa-miR-16 primer. When any results of detecting
stomach cancer CA (
Carbohydrate Antigen)19-9, CA24-2 and CEA (Carcino Embryonie
Antigen) of a patient by using serum are positive, and the
stomach cancer serological detection and identification kit provided by the invention is then used for carrying out aided detection, false positive results of serological detection can be effectively removed, so that huge
mental stress and property loss brought to the patient can be avoided; meanwhile, aiming at the situation that when the results of detecting the
stomach cancer CA19-9, CA24-2 and CEA of the patient by using the sera are negative, and the
stomach cancer serological detection and identification kit provided by the invention is then used for carrying out the aided detection,, the false negative results of the serological detection can be effectively found, so that the life of the patient can be rescued in time.
