There is nothing online about Tss in regards to thyroid function so whatever your doctor is basing your treatment on is clearly not working well if you went from a well treated patient to a symptomatic patient.
What about Tss? That's what she's basing my results on not the ths or t3 t4. She said my tss is low so she lowered my synthroid dose to 25
TSH stands for thyroid stimulating hormone. This test can help to diagnose and treat hypothyroidism but it has limitations for a variety of reasons. Using TSH alone for treating your thyroid symptoms may leave you undertreated.
