Biotin in high doses can interfere with certain medical tests. True or false?

Explanation:
High-dose biotin can interfere with many laboratory tests that use biotin-streptavidin detection. When large amounts of biotin are present in the blood, it can bind to streptavidin or to biotinylated reagents in the assay, disrupting the test signal and causing erroneous results. This interference can show up as falsely low results in sandwich-type immunoassays or falsely high results in competitive assays, depending on how the test is designed. Because several common tests (like TSH, troponin, and vitamin D) can be affected, it’s important for clinicians to know if a patient is taking high-dose biotin and to consider pausing biotin intake before testing if appropriate. So the statement is true.
