My daughter who is 18 took a Thyroid Gold Blue Horizon blood test a few weeks ago (please see photo attached).
She has really struggled with anxiety over the last 18 months and also at times previous to this. She has also been incredibly fatigued, which has been very tricky during A Levels. As both her grandmother and I suffer from hypothyroidism I have wondered if this could be an issue.
She is on Sertraline (100) for anxiety and also biotin for hair strength and renewal (as she pulls it out with anxiety) which I'm worried might have skewed her blood results (although she couldn't remember whether she'd taken the biotin before her blood tests when I asked her the day after!).
Her Cortisol seems very high - what might that mean??!
Should her Free T4 be higher in the range for optimal energy/health?
Any advice would be appreciated.

It's really important that she remembers about the Biotin . If it's a Biotin supplement it may be a high dose one, do you know what dose it is? It's the higher dose Biotin that causes false blood test results, the small amount in a B Complex may make little difference
Her cortisol is very high. Do you know what time of day she did the test? Hidden is our girl for blood cortisol tests so hopefully she will be around to comment.
Do either you or your mother have Hashi's? Her TPO antibodies are quite high in the range.
Her B12 is absolutely dire. She should ask to be tested for B12 deficiency and pernicious anaemia.
If she has any she should list them to discuss with her GP and insist on testing. If she's told her result is within range she must emphasise how low in range it is and that guidelines suggest that it's symptoms that should be prioritised over the result.
Her Folate is also very low but she should not take any folic acid or folate supplement until further testing of B12 has been carried out and B12 injections or supplements started.
A normal healthy person would have a TSH of no more than 2, often around 1, with FT4 possibly mid-range-ish. However, not knowing whether or not she took her biotin supplement makes it difficult to know if her thyroid results are reliable.
I have no idea whether the biotin your daughter takes has affected her cortisol test result.
If I assume it hasn't (not all testing machines are affected by biotin) then your daughter probably needs to be tested for Cushing's Syndrome because of her very high cortisol.
