Orthopedist says B12 tablets give false positives; internal medicine doctor refutes claim
Dr Amir Sanghavi states that B12 tablets can lead to false positive results due to their shorter duration in the body, but Dr Rituja Ugalmugle disagrees and suggests that routine B12 tests may not accurately reflect tissue-level deficiency. More sensitive tests are available, and injections may be better for certain individuals. Supplementation may still be necessary for certain groups.
