A urine iodine test measures iodine in a urine sample. This kit also measures creatinine, which the product page says is used to adjust the iodine result for urine concentration.
The ICPMS Iodine & Creatinine Test Kit uses dried urine collected on filter strips. The product instructions describe two collection times: first morning and last night. Iodine is analysed using ICP-MS, and the results are reported relative to creatinine.
Why measure creatinine with iodine?
Urine can be more or less concentrated. The product page explains that creatinine is used to help account for urine concentration when reporting the iodine measurement. Follow the collection instructions carefully so the samples can be interpreted as intended.
What can the result tell you?
The report provides a measurement of iodine in the submitted urine samples, together with specialist laboratory interpretation. A result alone does not diagnose a thyroid condition or determine whether you should take an iodine supplement. Review the result with a qualified healthcare professional, especially before changing your diet, supplements or treatment.
