Frequently Asked Questions

What are dried urine testing kits, and how do they work?

Dried urine testing kits are advanced diagnostic tools that allow you to collect and preserve urine samples in a convenient dried format. They work by soaking up urine onto a specialized paper or card, which can then be sent to a lab for analysis. This method provides accurate insights into various health markers without the need for traditional liquid urine samples.
