Serum and plasma are both important components of blood, and they differ in many ways.
First of all, serum and plasma are different. Serum refers to the liquid part of the tissue fluid that separates from the clot after the blood clots, while plasma is the liquid part of the blood that remains after the blood cells and platelets have been removed. As a result, the serum contains no fibrinogen and platelets.
Secondly, the composition of serum and plasma is different. There is no fibrinogen and platelets in the serum, so the components in the serum are simpler than plasma, only some proteins, hormones, and enzymes that are not present in the plasma. In addition, the amount of calcium ions in the serum is also higher than in the plasma.
Thirdly, serum and plasma function differently. Proteins, hormones, and enzymes in serum play important physiological functions in the human body, such as maintaining osmotic pressure, regulating metabolism, and immune response. The main function in plasma is to transport oxygen, nutrients, and metabolic wastes, among other things.
In addition, serum and plasma have different applications in different ranges. Serum is often used to diagnose diseases, monitor conditions, and evaluate the effects of diseases, such as measuring enzyme activity and immunoglobulin levels in serum. Plasma is often used for blood loss, blood volume replenishment and coagulation function.
In conclusion, although both serum and plasma are derived from blood, they have significant differences in composition, function, and range of application. Understanding these differences can help to better understand their physiological roles and clinical value.
