What Does This Blood Report Indicate?

Posted on Fri, 6 Nov 2015
Question: I have symptoms of hypothyroidism-fatigue, feeling cold, weakness, low mood. My GP recently sent me for a blood test. They only measured TSH which was 1.1 and free T4 which was 13. My thyroid looks enlarged to me. Could I have a thyroid issue?

Brief Answer:
Thyroid

Detailed Answer:
Sorry to note how you feel.

I have reviewed the attached photo. It is possible your thyroid has some enlargement but a physical examination is necessary to confirm this.

Regarding your TSH , it appears normal.

I would like to know the range of Free T4 on your laboratory report.

If the free T4 is well within normal range then it is extremely unlikely that there is anything wrong with your thyroid function.

Sometimes a thyroid ultrasound is required to study the thyroid structure in detail.

Many thanks for your response.
The lab reference ranges for free T4 are 9-19 so I am in the normal range. What do you advise I do next to get to the bottom of why I am feeling like this
?

Detailed Answer:
With normal Free T4 and TSH it is very likely that your thyroid is functioning fine.

Regarding your symptoms, other potential causes must be explored. A good start would be to run the following blood tests :

CBC
Electrolytes
Glucose
Liver function tests
Kidney function tests
Calcium
