How does thyroid hormone testing differ from a saliva test or a finger-stick blood test?
Saliva testing is an unproven technology and is not medically recognized by most accredited medical communities for thyroid assessment. Because the sensitivity of saliva testing hasn’t been clearly established, saliva testing has proven to be inconsistent and unreliable, not to mention more expensive. Finger prick spot blood tests are also unreliable and expensive and do not adhere to any medical standards for testing thyroid function.
