Question

what is the best test for b12 deficiency?
mma
hyper segmentation of neutrophils
d - xylose
schilling
question 10 (mandatory) (10 points)
blind loop syndrome is another name for sibo.
true
false

Explanation:

• For the first question: Methylmalonic acid (MMA) is a more sensitive and specific marker for B12 deficiency compared to the other options. Hyper - segmentation of neutrophils is a morphological change that can be associated with B12 deficiency but is not as specific as MMA. D - xylose test is used for other conditions like small intestine malabsorption (not specifically B12 deficiency). The Schilling test is less commonly used now due to radioactive tracer concerns.
• For the second question: SIBO (Small Intestinal Bacterial Overgrowth) and Blind loop syndrome are related. Blind loop syndrome is a condition where there is bacterial overgrowth in a non - functioning intestinal segment (a blind loop), which is a type of SIBO.

Answer:

• First question: MMA
• Second question: True
