This PDF (Mosaic Urine Collection Instructions) is a patient-facing instruction booklet from Mosaic Diagnostics (formerly Great Plains Laboratory) that explains how to collect, freeze, package, and ship first-morning urine samples for multiple urine-based tests (Organic Acids, Microbial Organic Acids, MycoTOX Profile, and other urine tests). Key actions: collect first morning urine (Mon–Thu; outside US Mon–Tue), confirm ordered tests and collect at least 10 mL per test, label samples with barcodes including date/time, freeze the sample for at least 4 hours (up to 30 days maximum), pack frozen sample with frozen ice pack in provided thermo bag and Test Kit Box, and ship per included instructions. The document also lists pre-collection dietary/medication restrictions for specific tests, gives an expected results timeline (~2 weeks after lab receipt), and provides customer-service contact details.
