Hi @Arnie Pye Level was 308 which was normal. But on the NHS nice website you linked above.. it says level between 100 and 400 you still should be referred to endocrinologist for further testing.
My hospital website has a page for each yest and how to use the result. It says for this test 300 and above *and no systemic illness* means no need to test further. It doesn't say what the threshold is if you have "systemic illness".
