    Does the boric acid in the Urine Monovette® also stabilise urine sediment?

    The Urine Monovette® with boric acid stabilises the microorganisms in urine.

    In principle, the parameters of urine sediment are affected by the pH value and the specific weight. The use of boric acid can therefore lead to cell lysis. The yellow Urine Monovette® without stabiliser is perfect for determining urine sediment. 

  • +

    What is the difference between the green and yellow Urine Monovette®?

    The colour-coding of the Urine Monovette makes it easy to quickly distinguish between the version with and without the stabiliser (boric acid).

    Yellow: neutral

    Green: with boric acid

  • +

    How is the Urine Monovette® with boric acid prepared?

    The Urine Monovette® is prepared with 15 mg boric acid/ml urine. This corresponds to a concentration of 1.5%. The preparation is free from mercury.

  • +

    Which Urine Monovette® can be recommended when using test strips for urine analysis?

    The Urine Monovette® 10 ml (product no 10.252) is suitable for urine analyses using test strips. The length of conventional test strips fits perfectly into a filled Urine Monovette®.

  • +

    What material is the Urine Monovette® tube made from?

    The Urine Monovette® tube is made from PP (polypropylene).

  • +

    Is the Urine Monovette® sterile?

    Due to the intended purpose, sterility is not required. For special requirements, the following individually packaged sterile Urine Monovettes can be ordered:

    Art. No 10.258.020 Urine Monovette® 8.5 ml (92 x 15 mm)

    Art. No. 10.252.020 Urine Monovette® 10 ml (102 x 15 mm)

    Art. No. 10.253.020 Urine Monovette® with stabiliser 10 ml (102 x 15 mm)

  • +

    Is the V-Monovette® Urine transfer unit sterile?

    No, if sterile transfer of the sample is required, the urine cup with integrated sterile transfer device can be used (Art. No. 75.562.400).

  • +

    Why does the Urine Monovette® with boric acid not have a scale?

    As the Urine Monovette® with boric acid should always be filled up to the nominal volume, a scale is not required. The filling level mark indicates the correct volume.

  • +

    Can the Urine Monovette® with boric acid be used for clinical chemistry tests?

    It must be assumed that the low pH-value will affect the test methods by providing false measurement results, as most methods involve enzymatic colorimetric tests.

    You can also obtain detailed information and any approvals regarding individual parameters from the manufacturer of the reagents.

  • +

    What is the minimum acceptable filling volume for the Urine Monovette® with boric acid?

    The Urine Monovette® with boric acid should always be filled up to nominal volume. For optimal stabilisation of microorganisms, underfilling should be avoided.

  • +

    For how long does the Urine Monovette® with boric acid stabilise microorganisms after filling the tube?

    At the correct filling volume, the boric acid stabilises microorganisms effectively between collection and analysis for up to 48 hours at room temperature.

  • +

    How should the Urine Monovette® be centrifuged for sedimentation?

    The recommended centrifugation conditions for sedimentation are 400 x g, 5 minutes at 20°C.

  • +

    Why is 24-hour urine collected?

    24-hour urine collection eliminates concentration fluctuations occurring throughout the day. It is therefore suitable for safely and reliably determining parameters which are subject to concentration fluctuations (circardian rhythm), such as catecholamine or creatinine clearance.

  • +

    What should be considered when collecting 24-hour urine?

    Collecting 24-hour urine starts by emptying the bladder in the lavatory. This time must be noted (e.g. 7 a.m.). 

    The next bladder emptying must be transferred to the collection container and, if necessary, the stabiliser is added (do not forget to mix). 

    Each subsequent urination must be collected until the following day. The collection stops from the time that was noted on the previous day (e.g. 7 a.m.). The bladder should be emptied shortly before in order to add this sample to the amount collected.

  • +

    What type of analyses require mid-stream urine?

    Mid-stream urine is particularly important for microbiological tests.

  • +

    What is mid-stream urine?

    After cleaning the external genitalia and after urinating for approximately 3 seconds, about 10–20 ml of urine is collected in a sterile container without interrupting the urine stream. Impurities are avoided in this way. Once the designated sample volume has been collected, the remaining urine can be released into the lavatory.
