Frequently asked questions
Is Serum Magnesium high or low in Migraine?
Reduced. Studies summarised in the OSMF atlas report lower Serum Magnesium in Migraine than in the reference group of the cited comparison (adolescents (age subgroup) with migraine vs age/sex-matched controls without headache). Source: Bhurat et al. 2022.
Which test measures Serum Magnesium?
The atlas record does not list a standardised clinical test code (LOINC) for Serum Magnesium, which usually means it was measured with research assays or study-specific protocols rather than a routine clinical panel. Check the cited source for the exact method.
Is one abnormal Serum Magnesium result diagnostic of Migraine?
No. No single biomarker is diagnostic of Migraine. Serum Magnesium findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
