Commonly used techniques for tumor marker detection include: enzyme-linked immunosorbent assay (ELISA), chemiluminescence immunoassay (CLIA), etc. However, if more detection techniques need to be expanded, more accurate point-of-care testing (POCT) can also be performed by fluorescence immunochromatography.
Diagreat can now provide a complete set of detection service solutions for the tumor marker of fluorescence immunochromatography platform, including: Total Prostate Specific Antigen Test Uncut Sheet (tPSA), Alpha-fetoprotein Test Uncut Sheet (AFP), Carcinoembryonic Antigen Test Uncut Sheet (CEA), Carbohydrate Antigen 125 Test Uncut Sheet (CA125), etc.
Fluorescence Immunochromatography Diagreat BIOTECH
Fluorescence Immunochromatography is a technology that uses fluorescent substances to label antibodies for antigen localization and is a new membrane detection technology based on antigen-antibody specific immune responses. The use of fluorescence can further improve the detection sensitivity. Compared with other immunoassay technologies, the most notable feature is its higher accuracy and sensitivity, so it is more widely used in precise quantitative programs.

· Total Prostate Specific Antigen Test Uncut Sheet (tPSA)
Elevated serum T-PSA generally indicates the existence of prostate lesions (prostatitis, benign hyperplasia or cancer), which can be used for screening and early diagnosis of prostate cancer in high-risk groups and monitoring the condition and efficacy of prostate cancer patients or patients receiving hormone therapy. The positive critical value of serum T-PSA quantification is greater than 10 μg/L, and the diagnostic specificity of prostate cancer reaches 90% to 97%, which has a great significance in assisting clinical diagnosis of prostate cancer.

· Alpha-fetoprotein Test Uncut Sheet (AFP)
The alpha-fetoprotein belongs to a kind of glycoprotein with a molecular weight of about 70KD. It is mainly synthesized and secreted by fetal yolk sac and liver. The guidelines for the diagnosis and treatment of primary liver cancer clearly state that serum alpha-fetoprotein (AFP) is a commonly used and important indicator for the diagnosis of liver cancer and efficacy testing.

· Carcinoembryonic Antigen Test Uncut Sheet (CEA)
Carcinoembryonic antigen (CEA) is an acidic glycoprotein with the characteristics of human embryonic antigen, present on the surface of cancer cells differentiated from endoderm cells. Carcinoembryonic antigen still has high clinical application value in the differential diagnosis of malignant tumors, condition monitoring, preoperative evaluation, curative effect evaluation, and recurrence monitoring.

· Carbohydrate Antigen 125 Test Uncut Sheet (CA125)
The detection of carbohydrate antigen 125 (CA125) is of great value in the diagnosis and differential diagnosis of ovarian cancer and other gynecological diseases. Comprehensive analysis combined with gynecological examination, imaging, pathology, etc. can achieve the purpose of early detection and early treatment.
