If
you are ever diagnosed as having a Thyroid problem, you are
going to want to familiarize yourself with some lab terms and
what all those numbers mean. Its not too complicated to
understand. Learning a little about labs will help you
with other illnesses as well.

How Labs Work:
In
a nutshell, a lab will draw blood from a vein in your arm.
Depending on the test they will be performing you might need to
fast (not eat) for 12 hours prior to the test.
Additionally, certain hormone tests are better to test in the
morning and others are better to test at night.
Once blood is drawn, the lab will do its thing and essentially
come up with a number for you depending on what they found.
That number will be placed within a reference range to show how
your blood looks in comparison to the average of other people.
For instance, the picture above is a snapshot of one set of my
labs. This set of labs shows my Hypothyroid and Hashi's
Disease. In this example, TSH has a reference range of .4
- 5.5. My score in this case was 9.119. |
