Verified step by step guidance1
Understand the difference between plasma and serum: Plasma is the liquid component of blood that contains water, electrolytes, proteins, and other substances. Serum is similar to plasma but lacks clotting factors.
Identify the components listed in the problem: Electrolytes, Albumin, Fibrinogen, and Globulins.
Recall that fibrinogen is a clotting factor. It is present in plasma but is removed during the clotting process to form serum.
Recognize that serum is derived from plasma after the blood has clotted, meaning fibrinogen is used up in the clotting process and is not present in serum.
Conclude that fibrinogen is the component found in plasma but not in serum, as it is involved in the clotting process.
