Tsh W Reflex To Ft4 What Is This Blood Test
HYPOTHRYOID: Your thyroid gland is underactive it is not producing enough thyroxine. The pituitary gland is working overtime to try to get the thyroid gland to produce enough thyroxine which regulates the bodies metabolic rate. You need supplementation of what your gland produces. You also need to be checked for autoimmune thyroiditis, see your doctor. ...Read more
Thyroid testing: The TSH level will be checked, and if it is out of the reference range, the lab will then run a ft4 without requiring the physician to call you in to have blood drawn again. ...Read more
What does "Tsh with reflex(reflux?) to FT4" mean with blood work?Does that mean it's as complete thyroid check?
No: TSH (Thyroid Stimulating Hormone) is a marker for thyroid function. If it is abnormally high, the lab automatically (reflexively) does a Free T4 level. This is useful for diagnosing hypothyroidism, but it is not the same as a full thyroid panel. Hope this helps! ...Read moreSee 1 more doctor answer

What kind of test I have to do to diagnostic a central hypothyroidism ? My TSH and ft3 are normal, but ft4 is low. Is that enought?
Pituitary tests: Central hypothyroidism is very rare, and typically occurs in association with other problems of the pituitary gland. You should have testing of other pituitary function (prolactin, lh, fsh, igf-1, estradiol, cortisol). You may need to see an endocrinologist for a proper diagnosis. ...Read more
Is it normal to have low levels of autoantibodies against your thyroid & 3.4 u/ml of autoantibodies against gad-65? What would this mean to a doctor?
No: While it may be common, it is not normal. Low levels show you have had prior thyroiditis, but do not say when or how severe. The gad antibodies are associated with development of type 1 diabetes. Check w/your doctor. Ps: why did you have these drawn in the first place? ...Read moreSee 1 more doctor answer
Im wondering if you can tell me what the ratio is for normal gluten levels on a blood test. This is mine glidan/gluten IgA ab 36 h2?
Testing for gluten: Sensitivity can be tricky, and should be done by a physician with the context of a good clinical history of diet and symptoms. The best way to definitively identify gluten sensitivity is to have a trial of exposure to gluten followed by endoscopy and biopsy of the small bowel. If there is good exposure to gluten and the small bowel is normal, then it is unlikely to be gluten sensitivity. ...Read more
Hi my TSH W/Reflex to FT4 is 4.54.. what does this mean? also my Cortisol is 26.8 what does this mean? thank you Kindly.
A cmp blood test says albumin/globulin ratio is 2.6 (says normal range is 1-2.1). What is this ratio, and what do results mean? Should i be concerned?
I wouldn't worry: High albumin doesn't occur except in dehydration which also raises globulin, so your total globulin is a bit low overall. Chances are you're one of the folks who makes less in the way of antibodies than other folks, at least right now. This level's no danger to you. These investigations are seldom productive and if you feel well, I'd simply be thankful for good health and keep an eye on it. ...Read moreSee 1 more doctor answer
My Tsh w/reflex t-4 free is 6.25. What that mean? Is my thyroid gland hormon low? Thank. Not yet medication, doctor said to come again for 3 months
6.25: Sorry, but each laboratory has a different reference interval for each test including thyroid studies. Till you know the normal range for your thyroid lab you won't know whether the result is good or not so good. Your doctor should have that information. ...Read more
What to do if I had a blood test,,then,,the result for hepatitisbs ag is reactive (low titre),,whats mean by dat?
Hepatitis B: The presence of He B surface antigen may indicate acute or chronic Hep B infection. You need to have a more complete panel, with Hep B core antibody and Hep B surface antibody checked. In chronic infection you would have positive surface antigen and core antibody, but no surface antibody. You would then need further evaluation, with Hep B viral load, e antigen and antibody, and liver enzymes. ...Read more
Thyroid tests: It is advised that you would benefit from an online consultation to review your labs as well as past medical history and discuss your specific symptoms. A physician can help you understand the labs, correlate with your history and make recommended next steps. ...Read more
Normal: That's a normal value. That's why they didn't have to run the free t4. Reflex means they will run ft4 only if tsh is abnormal. ...Read more
My hepatitis C antibody test is non reactive and my signal c/o ratio is 0.01. Do they use the signal to cut off ratio even if antibody test is negativ?
Yes: The lab uses a signal to cut off ratio (scr) to try to determine whether a signal is "noise" or real. Your scr is very low, and the lab accurately defined this as a negative response. Note, people can have a high scr and still not have chonic hepatitis c infection. ~25% of people will spontaneously clear hcv after infection. They are left with antibodies but the hcv RNA (viral load) is negative. ...Read more
