Experimental analyze of identification of blood samples using the light sensor

In this fast world we should need to know the blood group and type. So quick and perfect identification of blood sample is very important during the urgent situation. This future proposal is to change the physical work in medical laboratories for identifying the blood sample. Usually, the blood group analysis is made in the laboratories and there are three types of blood group analyzing methods, they are ABO forward typing, ABO reverse typing and Rhesus type testing. In the laboratories ABO type and Rhesus type testing techniques are mainly used. In the ABO testing method is used to identify the blood sample group. In the Rhesus testing method is used to identify the positive and negative of blood group.Even though it is easy to identify the blood group of single sample blood, but when handling the large number of blood samples, it might lead to wrong analysis. In order to solve this problem and reducing the manual involvement and to get better reliable result, we design the machine which will automatically identify the blood group based on the application of Infra Red (IR) light source. When the IR light is focused towards the blood sample, the light intensity is changed due to the blood darkness. It will be sensed by the IR light detector. The blood group and type can be identified by the intensity value of the light.
