The CDC classifies Washington DC, Maryland, and Virginia as high-incidence areas for Lyme. Standard two-tier blood testing catches only 22 to 36 percent of early infections, so a negative result does not rule Lyme out when symptoms are present. Free state and county programs identify a tick's species but do not test it for disease, and broader co-infection testing is not routinely ordered.
Hashimoto's is diagnosed by combining findings, not one test: thyroid antibodies (TPO, sometimes thyroglobulin), thyroid function (TSH and free T4), symptoms, and often an ultrasound. A normal TSH does not rule it out, and a low-positive antibody is not always disease. Found early, before the gland is damaged, there is the best chance to protect it and feel better.
There is no single Hashimoto's diet, but a few moves have real evidence. Correct the nutrient gaps you can measure, like iron, selenium, and vitamin D. Get your iodine to the right level, which takes an assessment, not one test. And cut a food only for a real reason, like a positive celiac test or too much iodine. Assess first, then personalize.
