You did not send normal values for your lab. Be certain u emit taking Biotin which can mess with tests depending on assay they use. Go to uptodate.com and read more.

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your TSH suggests thyroid deficiency and you should talk to your doctor about your medication or adjustment to the dose of thyroid replacement medication. Wish you good health!
