Brief Answer:
No
Detailed Answer:
At first glance, you do not seem to have hypothyroidism.
TSH is a very reliable screening test to detect the vast majority of individuals with thyroid problems.
So statistically it is extremely likely that your thyroid is normal based on the normal TSH of 2.51
However, there are some uncommon conditions in which the TSH looks normal but the other thyroid related hormone levels suggest other possibilities such as 'Central hypothyroidism' which is a very uncommon type of hypothyroidism.
So it is important to study the results of Free T4, Total T3 also for example. I see you have given values of these. But the normal ranges and units for measurement vary from lab to lab. It is very important therefore to know if the lab results for these fall in the normal range for the laboratory where you had these tests done.
If these are also within the normal range, as is the TSH then it is extremely unlikely you have hypothyroidism
No

Ok. Thank you.
My T3 uptake is 30 ( lab range 24-39)
My T4 is 1.08 ( lab range .82-1.77)
Ive recently read that TSH OF 2.5 ( lab range .450-4.5) are high. And some drs suggesting the TSH NOT exceed 1.5. Ive dine these tests abs asking these questions before meeting with new prinary next week so that i can cinsider other opinions

Brief Answer:
Follow up
Detailed Answer:
I have noted your response.
I know what you are referring to regarding TSH 2.5 also being considered high by some.
Based on the bulk of the scientific evidence, as of now TSH of 2.5 is deemed normal.
When I diagnose a person with hypothyroidism though, I aim for a TSH on treatment with XXXXXXX thyroxine, of around 1 or thereabouts. This may seem paradoxical to you but this is where the current treatment guidelines stand.
