New Test Identifies Blood Type in Seconds
New Test Identifies Blood Type in Seconds
 Scientists working at the*Third Military Medical University in Chongqing, China have developed a tech**logy to quickly identify a Blood sample’s Blood type. It relies on using antibodies that target A and B antigens that give Blood its type, and a dye that is activated when the antibodies are in attack mode. The same was done for the D antigen, which gives the plus or minus to the Blood type. The sample is placed on a plate with a combination of antibody and dye, and the color of the plate changes depending on if a reaction is occurring. It stays brown if **thing is happening. A single Test takes only 30 Seconds to provide a result, which can be highly useful in emergency situations in which transfusion needs to be initiated as soon as possible. The team tested the technique on over 3,000 k**wn Blood samples, demonstrating an accuracy of 99.9%. Study in Science Translational Medicine:*A dye-assisted paper-based point-of-care assay for fast and reliable blood grouping… Image caption:*(A) ABO forward strip, (B) F&R assay, and (C) ABO and Rh group multiplex antigen assays. I and II represent the forward blood-grouping observation *******; III and IV represent the reverse blood-grouping observation *******. The observation zone is located between the two dotted lines as shown in the platforms of the ABO and Rh group assays (C). A strip without antibody (BCG only) was used for quality control (QC).
