I've just read an article from US Clinical Interventions in Aging which based on several studies is suggesting the following:
'In elderly people, low levels of TSH or high levels of FT4 that are still in the normal range are associated with higher mortality, but the same is not clear for high levels of TSH or low levels of FT4.'
I thought that the opposite statement would be more true. What do you think of this and the studies supporting the statement?
Another interesting part of the article:
'Due to the increased prevalence according to age and the impossibility of ruling out the diagnosis without laboratory measurements, several guidelines recommend routinely screening for thyroid diseases after a certain age. The American Thyroid Association recommends screening both women and men at 35 years of age, and every 5 years thereafter.
The American Academy of Family Physicians recommends thyroid screening for patients over 60 years old, independent of gender and the American College of Physicians recommends high-risk strategy for people aged over 50 years with nonspecific complaints.
In contrast, other institutions such as the US Preventive Services Task Force, the Canadian Task Force on the Periodic Health Examination and the British Royal College of Physicians do not recommend routine screening for adults or for the elderly. The Institute of Medicine evaluated evidence for a benefit of screening for thyroid disorders in the Medicare population but decided against screening based on a cost-effectiveness analysis.'
Does that mean that our NHS routinely checks for thyroid function only at birth?
