Description
The term Kryptopyrrol test is the old name for a test that measures total pyrroles. Nowadays, most laboratories call this test the total pyrrol test. The measured value is expressed as a number.
(Krypto)pyrroluria can occur to anyone at some stage and period of life, such as after pregnancy, prolonged illness, infection, exposure to heavy metals or an accident. The body often regenerates on its own, but this is not always the case. The basis for the lack of regeneration is a deficiency of some B vitamins (B1, B2, B6) and certain minerals (zinc, magnesium).
A 24-hour KPU test is more reliable than a morning urine test for adults over 22 years of age. We recommend a morning urine KPU test for all children and adolescents under 22 years of age.
