Miscellaneous instructions for the collector
Start time: Discard the first-morning urine and record the date and time. This is the start of your 24-hour period.
Collection timing: Collect all urine for the next 24 hours. If your start time was 9 a.m., you would collect urine up until 9 a.m. the next day.
Important note on PCR: While osmolality is a common test, it is different from urine PCR testing, which is used to detect genetic material from pathogens. The instructions for a 24-hour urine collection for osmolality are distinct from those for a single urine sample for PCR, which typically uses a clean-catch, midstream sample.
Special considerations: If your healthcare provider has given you any specific instructions, such as a special diet or avoiding certain medications, be sure to follow them precisely.
