Question

Why in most blood test's the word serum is used instead of blood?

Answer 1

Serum is the most preferred part of blood used in checking blood groups and diagnosis of diseases whereas plasma is delivered to the patients who lack blood cells. Like fresh frozen plasma is used in Hemophilia B. It can also be used for diagnosis of diseases.

Answer 2

Semen analysis, also known as a sperm count test, analyzes the health and viability of a man’s sperm. Semen is the fluid containing sperm (plus other sugar and protein substances) that’s released during ejaculation. A semen analysis measures three major factors of sperm health:

the number of sperm

the shape of the sperm

the movement of the sperm, also known as “sperm motility”

Doctors will often conduct two or three separate sperm analyses to get a good idea of sperm’s health. According to the American Association for Clinical Chemistry (AACC), the tests should be conducted at least seven days apart and over the course of two to three months. Sperm counts can vary on a daily basis. Taking an average of the sperm samples can give the most conclusive result.
