Acth stimulation test results accurate?

Depends: I'm assuming no lab errors. If you get a very high cortisol spike after receiving the first dose of ACTH, you are reassured you do not have Addison's. No, or a very small spike, strongly suggests Addison's. In-between... that's why there are specialist endocrinologists. ...Read more

Ok: Most ivf clinics only measure HCG levels approximately 9 days after a day 5 embryo transfer. However, some clinics feel that the combination of HCG levels and Progesterone levels have a more predictive value of a good pregnancy than HCG levels alone. Personally, we only measure hcg. Hope this helps and good luck. ...Read more
