Worried about blood test results

Am newly diagnosed hypothyroid but while the diagnosis process was ongoing, I was referred to a neurologist who sent me for loads of blood tests. Just got some results today and they want to retest two as they are slightly over range (no figures given). One is my globulin which is part of liver function tests and the other is my APTT - i have a slightly prolonged clotting time.

Anyone know anything about these? Could they relate to my misfunctioning thyroid?

They're not thyroid related tests.

Globulins are a group of proteins within the blood. They are produced by the liver and the immune system. Albumin makes up more than half of the total protein within the blood, and globulins make up the remainder.14 May 2014

What is activated partial thromboplastin time?

Test Overview. Partial thromboplastin time (PTT) is a blood test that measures the time it takes your blood to clot. A PTT test can be used to check for bleeding problems. Blood clotting factors are needed for blood to clot (coagulation).

Thanks I have already googled so understand what they are to a limited extent. Was wondering whether anyone had any experience of yhese tests abd what they showed fir them. Also wondered whether misfunctioning thyroid could cause other abnormal blood tests eg liver as thyroid hormones are needed by every cell in the body so presumably other parts of you could start to go wrong?

I am taking k2 mk 7 with my vit d, could this be causing delayed clotting?



Thyroid dysfunction can affect liver function.

I don't know whether K2 Mk7 affects blood clotting. Perhaps Google will help.


It does state this is side effects tab:

Liver disease: Vitamin K is not effective for treating clotting problems caused by severe liver disease. In fact, high doses of vitamin K can make clotting problems worse in these people.


It is supposed to be K1 which affects blood clotting, not K2 (and it makes it clot faster), so unlikely to be that - omega 3 oils perhaps?


Not taking omega 3s at the moment. 🤔


I don't know about these specifically, but have been called back for a lot of different blood tests, and possible other diseases while hypo, and know lots of people on the forums have been diagnosed with all sorts of things.

In general thyroid affects every cell, tissue and organ in the body.


It is not known now, whether vit K2 affects clotting, but I have read that this highly suspected by scientists. How much are you taking? Perhaps you could lower the dosage.


I'm taking 5000iu with 100mcg K2 mk7 every other day. It's odd because I can't do fingerprick tests because my blood clots too quickly!


It might be wise to get the entire picture. Thyroid can be the effect from, as well as the cause of other health problems.

Then, coming up with a comprehensive treatment plan, rather than having different specialists working in stovepipes, may prevent unexpected consequences and give you the best outcome.
