TSH , 3RD generation with reflex to FT4?

[Cassylou]

What is this test? I had this test done last month among others and this one came back as 7.46 mIU/L and the reference range is 0.40-4.50 . Dr. Wrote "elevated-over 7."
Also my calcium was high at 10.6 mg/dL and reference range from 8.6-10.2
Free T3- 4.3 ph/mL reference range from 2.3-4.2 , slightly elevated.
T-4, free- 1.5 B&G/dL reference range from 0.8-1.8

My main question is what is the tsh 3rd generation with reflex to ft4?

[Barb135]

What test are you referring to?  Is it a TSH test?  Is that the only test you had done?

[catnar]

My test was 1.20 is that good or not

Ok so what tests should I have done? I want to make a list of all of them for when I go in next

Vitamin B12 is a necessary for the formation of red blood cells, which carry oxygen throughout the body.  It's also necessary for healthy nerve function. Many of us don't absorb B12 adequately and we become deficient.  B12 deficiency can cause horrible fatigue/lack of energy. If left untreated, it can cause numbness, tingling, pain in the hands, feet and legs.  I had untreated vitamin B12 deficiency for so many years, that I have permanent nerve damage (peripheral neuropathy).  

Vitamin D is necessary for proper absorption of calcium and it's also necessary for proper metabolism of thyroid hormones.  Vitamin D deficiency can cause many hypothyroid like symptoms.

Most of us have 4 parathyroid glands.  They reside just behind the 4 corners of the thyroid gland, but their purpose has no relationship to the thyroid gland.  To explain it simply, their purpose is to control the movement of calcium into and out the bones.  Aside from being necessary for bone formation, calcium controls electrical impulses in our body.  Sometimes, one (or more) of the parathyroids can malfunction.  This is usually evidenced by high blood calcium.  You should ask your doctor to test Parathyroid Hormone (PTH) to make sure everything is okay there.

I've never had tests done for vitakin b12 or vitamin D and I've never had tests done for parathyroid issues either. I've never even heard my doctor bring parathyroid issues up. What is it?

[Barb135]

Has your PTH been tested to see if you might have parathyroid issues?  What about vitamin D, which figures into parathyroids?  Are you supplementing vitamin D?

[Barb135]

Your symptoms certainly indicate hypo, but your labs don't, except TSH.  I wonder if you have resistance to thyroid hormones at the cellular level.  In other words, you have plenty of hormones in your blood, but they aren't getting into your cells where they can be used.

I'm going to ask a couple other people to take a look a this and see what they think.  

Have you had vitamin B12 levels tested?  B12 deficiency can cause the most horrendous fatigue/lack of energy you could ever imagine.  Ask your doctor for that. Just being "in range" isn't good enough.  Your level needs to be very near the top.

I've had thyroid problems for 4 years and I've been on 25mcg levothyroxine since the beginning. I was diagnosed hypothyroidism in 2012 and diagnosed with hashimotos the same year. When I recently went in for these lab tests my thyroid was enlarged and there is a possible nodule on the left side. My doctor isn't sure how to regulate my meds because I'm tired 24/7, no energy, mood swings, and my hair is falling out like crazy. so she is sending me to get an mri done to look for a tumor/mass.

[Barb135]

When the doctor orders TSH w/reflex to FT4, he's telling the lab to analyze TSH and if it's abnormal they should run FT4.  If TSH is normal, that's as far as they should go.  Your TSH was abnormal - meaning outside the reference range, so the lab analyzed Free T4.

Please check the units for the FT3 and FT4.  I've never seen ph/mL or B&G/dL.  They're usually ng/dL or pg/mL, etc.  

Are you taking a thyroid replacement medication?  Your TSH is over the upper end of the reference range, but your FT4 is in the upper portion of its range and your FT3 is over the upper end of its range.

Do you have symptoms of either hyper or hypothyroidism?  What prompted this testing?
