Thank you. I will definitely check into these other labs. I was unaware of the connection to the pituitary..
I do think you should look into Hashimoto's first.
Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TGab) to test for Hashimoto's
Other tests that might be helpful are:
Prolactin, Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Basic Metabolic Profile (BMP), ACTH, for pituitary testing.
But since you have PCOS, you might already have been tested for some of these, so check previous lab reports to make sure you don't duplicate.
Thank you both for your input. It is greatly appreciated!
So you feel with my free T3 and TSH being within "normal" range, I should still look into Hashimoto's first and not pituitary? I have the lab slip to check for the antibodies so I will def do that.
What other tests are done to check into the pituitary as the culprit?
Thanks very much. This forum has been extremely helpful!
I agree that you need the antibody tests to see if you have Hashimoto's.
The notation regarding the reagent means that the result is 9% higher than previous batches of reagent had shown. Therefore, if I calculated it correctly, previous reagents would have come up with a result of 0.91 vs 1.0.
There is some question as to whether those not on thyroid med need levels as high as those of us dependent on med, but since you have so many symptoms, I'd say your levels are not nearly high enough for you.
There's controversy over whether or not blood cortisol levels are helpful, since that is usually tested only once and cortisol raises and lowers according to a circadian rhythm. It should be highest in the morning, as we prepare to go about the day, and gradually drop off as we prepare to sleep at night. Supposedly, a 24 hr saliva test is the only way to check this, accurately and most doctors do not do the 24 hr saliva test.
I'm not sure I'd be looking at a pituitary issue just yet.
Vitamin B12 is the # 1 thing to check when fatigue is a prevalent symptom, as it can cause the most debilitating fatigue you can imagine. It can also cause brain fog and memory loss, along with tingling/numbness in the feet/hands.
As FTB4 noted, an iron work up would also be good.
Do be aware that thyroid issues, along with B12 deficiency (Pernicious Anemia) often go hand in hand with PCOS. Your glucose and insulin levels look good, but do be careful to eat things low on the glycemic index in order to prevent blood sugar spikes, which in turn produce insulin spikes, which in turn produces weight gain and eventually type II diabetes. That one becomes a vicious circle.
Your thyroid hormone levels may be in range but they are low, TSH is low also, and it should be higher with low thyroid although it is a Pituitary Hormone, but Your Free T4 is only 20% in its range, Your Free T3 is higher (As it should be) at 42% of its range, but should be higher. I would think you would feel much better with Free T3 higher at or around 65-70% and Free T4 at least 50%, That is where someone with Hypothyroid on medication would feel best at, so I would assume that would even apply to a person not on thyroid meds. Its easy for an MD to look at your results and say "Your in range, so your thyroid is OK" We hear that all the time with MD's that don't treat symptoms, and treat by lab ranges. Free T3 is the active hormone that controls your body's metabolism, which in turn has a direct affect on weight gain or loss and energy levels. I would advise you to request tests for Thyroid Antibody tests for Hashimoto's Thyroiditis which are Tgab and TPOab you could be in the beginning stages of this common cause of Hypothyroid Disease. These tests will prove or disprove,
Low Ferritin and low Iron Levels can cause low thyroid levels and symptoms also, so these tests would be needed along with two other tests for deficiency's in Vitamin B12 and Vitamin D, I assume the notice about the reagent used in testing throws off the result by 9% so for Free T4 you would add the 9% to the 20% = 29% in range. If you have any more results or questions do not hesitate to ask. Best Wishes FTB4
Also, under the T4 free it says "The current lot of free T4 reagent available from the manufacturer produces results that are approximately 9% higher than previous reagent lots. Please interpret these results accordingly"
Not sure if this effects anything?
