Blood characteristics

These components are found in the blood of all human beings, but the blood itself differs from person to person, With blood, which we will learn during this article.
blood types
The blood type is an antigen found on the red blood cells. There are three types of antigen: A, B, AB. The A group, on which blood groups are determined, (O) In the absence of any of the types of antigens on red blood cells, the blood type of the type (B), and thus there are four blood groups, namely (A, B, AB, O), and each person carries a blood type of These four species, however, can only be identified when a blood analysis is performed in the laboratory.
Method of blood type analysis
- We bring a glass slide and place three dots of the three solutions (Anti A, Anti B, Anti D); we place one point of each solution on one end of the slide.
- Place a point of blood to determine the type of faction on each solution:
- If blood groupings and antigens (B) are observed, the blood type is (AB).
- If blood is collected with anti-A alone, the blood type is (A).
- If blood is collected with an anti-B solution only, the blood type is (B).
- If blood drop is not given to any antiviral group (Anti A, Anti B), the blood type is (O).
