Blood plasma without the clotting factors is called as _____________.

Serum

Explanation:

Blood consists of various components, including red blood cells, white blood cells, platelets, and plasma. Plasma is the liquid portion of blood that serves as a medium for transporting nutrients, hormones, and waste products throughout the body. It contains several proteins, such as albumin, globulins, and fibrinogen, which play crucial roles in maintaining osmotic balance, immune responses, and blood clotting.

When blood is allowed to clot, the clotting factors, primarily fibrinogen, are consumed in the formation of the clot. The remaining fluid, which lacks these clotting factors, is known as serum. Therefore, plasma without clotting factors is called serum. Serum retains other essential components like electrolytes, antibodies, antigens, hormones, and any exogenous substances (e.g., drugs, microorganisms) present in the blood.

Understanding the distinction between plasma and serum is vital in medical diagnostics and research. Serum is commonly used in various diagnostic tests, including blood typing and measuring the concentration of different molecules, which can aid in diagnosing diseases and monitoring health conditions.
