Hello dear sir/madam,
Last June, I underwent a full-body blood test, and most results were normal. My
TSH was 3.9, and
Vitamin B12 was 212. My doctor explained that, since I work night shifts, stress might have contributed to these borderline values. She advised me to repeat
thyroid and B12 tests every 2–3 months. Over the past year, I’ve done three follow-up tests, with TSH levels of 3.7, 3.2, and 3.1, while B12 has remained around 230. Given this trend, how frequently should I continue these tests. I am not under any medication and i dont even have any symptoms.
Kindly advise.
