Serology is the study (mainly) of blood. By being a serologist you won't be only testing blood, you would also be testing urine, saliva, and/or other bodily fluids. The study of blood is for the purpose of helping solve crimes like homicide, rapes, assaults, and paternity disputes.
How to Find Blood
CSI's will use an agent called luminol, which will detect any traces of blood that have either been cleaned or faded. When luminol has been sprayed, it requires a fairly dark to be detected, and will only last for 30 seconds. The agents in the luminol will react with the iron in the hemoglobin's.

Different Parts of Blood
The human blood is made up of 4 different parts: red blood cells, white blood cells, platelets, and plasma. Each part of the blood has a very important role in helping the body survive. The red blood cells carry oxygen from the lungs to the rest of the body. White blood cells help to fight off infections on the body. When platelets are combined with other materials, they will clot the blood so we can't bleed to death. Plasma transports excess waste around the body so it can be released in the proper manner.
The amounts of Red blood cells (RBC's), White blood cells, (WBC's) Plasma, and Platelets.
There are 4 main categories for blood, there is AB, (which id most common with Asian people) A, B, and O. For each of these categories there is a sub-category. Each blood type has a positive and a negative, for example: O+, A+, B+ and AB+ then there is O-, A-, B-, and AB-. For the majority of the countries in the world, there is a higher population of people with O+ blood. The few exceptions are: Austria, Denmark, Estonia, Finland, France, Germany, Israel, Norway, Poland, Portugal, Sweden and Turkey.
