I append a paper which doubts the value of urine T4 measurement to distinguish euthyroidism and hypothyroidism.

Personally I think blood tests are more reliable but of course subject to proper accompanying diagnostic procedures.

Daffers, A lot of members are able to interpret TSH, FT4 and FT3 blood results but I've not seen anyone able to interpret urine results.
