Results interpretation

[susieq19642002]

TSH .865 (0.450-4.500)uIU/ml)

t3,free 2.7 (20.-4.4 pg/ml)

free T4 .71 (.82-1.77 ng/dl)

I would like to know what these levels mean. Is my thyroid currently under active or over active?

They also did a hapatic function panel which noted a high alkaline phosphatase level 160 (39-117 IU/l)

Hi susieq, it is hard for us to say without the reference ranges. They look something like this tsh 0.865 ( 0.4 - 4.2) post them for each reading you have.

[susieq19642002 in reply to Greybeard]

Why aren't reference ranges the same for every one?

[Greybeard in reply to susieq19642002]

The reference ranges are particular to the assay machine the tests were run on.

I believe because various labs purchase their instruments for running laboratory tests from different manufacturers. This use to be a hugh problem for patients on the anticoagulant Coumadin (or Warfarin) who traveled, so a "INR" or International Normalization Ratio was established so their lab test could be performed in different countries with standardized results.

Susieq19642002,

If you are not taking anti-thyroid drugs for hyperthyroidism you are hypothyroid because Free T4 (FT4) is below range.

TSH is low in range which rules out primary hypothyroidism so your GP should consider secondary or tertiary (central) hypothyroidism and prescribe Levothyroxine. In the UK it is recommended that central hypothyroidism patients are referred to endocrinology for management as sex and growth hormones need testing to rule out deficiencies too.
