Precision urine collection that reduces contamination and delivers reliable results.
Peezy Midstream provides guideline-compliant, precision urine collection to reduce urine specimen contamination and false positives for women’s UTI and prenatal screening. It delivers proven clinical and service benefits to healthcare providers, as well as cost savings and a cleaner, kinder patient experience.
As with any novel diagnostic system, we recommend a short face-to-face explanation for those using Peezy Midstream for the first time, after which the process is intuitive.

Research on Peezy Midstream may reveal a 2021 study from Oxford Nuffield published in the British Journal of General Practice. This study did not provide parity of instruction to each arm, and the author confirms that full bladder was not ensured.
You can read the paper here together with Dr Vincent Forte’s response.
As a result of this trial, we have improved our Instructions for Use, making the need for a full bladder more pronounced.
