I'm impressed with the service and so pleased I had it done, the results speak out don't they! The Vit. D, I'm obviously over-supplementing so I can reduce that. I curious about the remarks about the T3 because I have taken some recently but it ran out over a week ago or more and I thought that would be long enough to wait before doing the test as I read it doesn't have much of a life? Here's the comments, I have to chuckle about seeing the GP, I suppose they have to say that.
"The free T4 level is low. In the presence of a normal thyroid stimulating hormone level (TSH), and normal free T3 level it would not surprise me to learn you are taking liothyronine (T3) instead of levothyroxine - is this the case? If you are taking a form of thyroxine medication already, you may need to adjust your dose – a discussion with your usual doctor would be sensible. If not, I also suggest you make an appointment to see your doctor – at least surveillance of thyroid function would be wise, as it would seem in this scenario that an underactive thyroid gland might be developing.
The level of Vitamin D is elevated and usually this would be a sign of excess supplementation - if this is the case, dose reduction is advisable. High levels of Vitamin D may also occur when there is excess parathyroid hormone or in certain rare diseases in which this form of vitamin D is manufactured outside the normal site of production (the kidneys). Sarcoidosis and lymphoma can give rise to this situation, albeit rarely. If supplements have not been taken recently, further testing may be indicated, at least of parathyroid and calcium levels. I advise you to make contact with your usual doctor at your earliest convenience if this is the case.
The ferritin level is high. In addition to excess iron supplementation, raised serum ferritin can be a sign of inflammation or infection, though in your case the normal level of CRP would suggest that the latter possibility is unlikely. Less commonly, higher ferritin levels can result from damage to bone marrow or liver, genetic conditions, following blood transfusion, and in chronic anaemias such as thalassaemia. If it is unlikely that iron supplementation is the cause of this elevation then more formal iron studies would be useful. I suggest you discuss this result with your usual doctor who may recommend further tests.
My ferritin is still off the scale and I've made a real effort to avoid sugar and carbs and have lost some weight as a result. Curious.
