Only loosely related, but are there any affordable non-invasive tests for past lead exposure? I have a cluster of symptoms that are consistent with lead exposure[1], along with a lot of past activities involving lead (stained glass, old-school electric cars, soldering with lead-based solder, stripping lead-based paint), but my current blood lead levels are normal. My neurological symptoms also flared up when I was supplementing with kind of a lot of Calcium and Vitamin D. [1]mostly high blood pressure, somewhat high cholesterol (despite having normal BMI, sleeping reasonably well, exercising regularly) and demyelinating lesions visible on MRI (but no oligoclonal bands, negative AQP4).
