Blood type of test can determine your blood type in just 30 seconds
The current methods of determining patient’s blood type involved a complicated procedure that lasted between 10 to 20 minutes, and that’s even without the additional time that potentially had to be spent on transport of blood to the appropriate testing facilities. To avoid waiting time and possible mismatches, many hospitals stockpile large quantities of universal donor type O blood, which makes this blood type to be in great demand, straining the potential donors and causing hospitals to accept lower amounts of donations of other blood types.
A new type of blood test has a potential to change current procedures and state of blood banks in hospitals. Developed at Third Military Medical University in China, this new form of blood tests uses only a paper-based solution that can without the presence of any other specialized equipment determine patient’s blood type in just 30 seconds. This new procedure represents a significant breakthrough that will enable hospitals all around the world to perform quick tests in life-or-death situations where any delay in procuring the compatible blood type, ease up demand for type O blood, enable easier blood tests in the areas where medical labs are too far away, and also provide a viable way of determining patient’s blood type in war zones or by in-the-field medical personnel.
The chemical reaction that determines the patient’s blood type is very simple and involves the reaction between blood serum proteins and the common dye that has the presence of antibodies that can detect which blood type is interacting with them. Once the blood touches the prepared paper strip, it changes color in the following ways – teal of the tested blood has antigen present in it or blown if the blood does not have antigen. This procedure was tested in more than 3550 samples of human blood and was found to be more than 99.9% accurate.
