Question

which of the following markers would help you the most if you were trying to determine if the patient had iron deficiency anemia?
a) ldh 1
b) serum ferritin
c) tibc
d) total bilirubin
e) hgba1c

Explanation:

Serum ferritin is a key marker for iron - deficiency anemia. It reflects the body's iron stores. Low serum ferritin levels (usually < 30 ng/mL) are highly indicative of iron deficiency. LDH 1 is more related to hemolysis (e.g., in some types of anemia due to red blood cell destruction). TIBC (Total Iron - Binding Capacity) can be elevated in iron - deficiency anemia but is not as specific as serum ferritin. Total bilirubin is more relevant in conditions like hemolytic jaundice or liver - related disorders. HgbA1c is used to monitor long - term blood glucose levels in diabetes.

Answer:

B. Serum Ferritin
