What should I do if I cannot obtain a stool sample without assistance?
Sample Collection & Handling
If a stool sample cannot be obtained naturally and an aid must be used, best practice is always to minimize contamination whenever possible.
Preferred option (if an aid is unavoidable):
Saline enema
Saline is the least likely to interfere with microbial DNA or biomarker analysis. If a saline enema is used, allow excess saline to pass and submit formed stool only (not liquid).
Options to avoid when possible:
Glycerin suppositories: Glycerin is not recommended, as it may alter stool composition and interfere with test results.
Urine contamination: Urine should be avoided, as it can dilute the sample and compromise sample integrity.
Important note:
Stool samples collected using enemas, suppositories, or other collection aids fall outside standard collection recommendations and may impact test performance or interpretation. The laboratory cannot guarantee result accuracy for samples collected with collection aids or contaminated by urine or other substances.
If you have concerns about sample collection, we recommend discussing options with your ordering provider prior to submission.
