Q: Female, 29 years old, one year ago (2009-8) because I was planning to have a child, I had a full body checkup and was inadvertently tested for subclinical hypothyroidism, the labs at that time were within the normal range for FT3 and FT4, only the TSH was higher than normal by 2. The doctor here told me to take 1/4 tablet of Eugenol daily, and after taking it for one month, the lab results were within the normal range, so I stopped taking it and never took it again. I got pregnant 7 months later (on the first day of my last period on April 10, 2010), and have been pregnant for 4.5 months now, and I have been checking every month, and they are all within the normal range. 1. Is it true that FT3, FT4 and TSH are all within normal values, regardless of whether they are at the upper or lower limit, they are considered normal and no medication is needed? 2. If TSH is within the normal range, but FT3 or FT4 is lower than normal, should I start taking medication as well? 3. In my case, do I need to have a special test for my child after birth? Or will the hospital test my child’s nail function and I don’t need to ask for it? 4. Do I need to have my blood tests repeated every month during breastfeeding as well? A: If FT3 and FT4 are within the normal range and TSH does not exceed 2.5, you do not need to take Eugenol. For primary hypothyroidism, the situation you mentioned (normal TSH, low FT3, FT4.) will not occur. TSH is routinely checked in the hospital after the child is born.
