How long is the blood flow rate reduced before obtaining a post-dialysis blood specimen for KT/V?

In the context of obtaining a post-dialysis blood specimen for KT/V measurement, it is critical to ensure that the blood flow rate is appropriately managed to obtain accurate results. The recommended practice is to reduce the blood flow rate for a specific duration before collecting the sample. Reducing the blood flow rate for 15 seconds allows for adequate stabilization, ensuring that the specimen reflects the patient's condition accurately after dialysis.

This practice helps prevent the dilution effects that can occur from residual dialysate in the bloodlines and ensures that the sample taken is representative of the blood status post-treatment. By following this guideline, healthcare providers can enhance the validity of the KT/V measurement, which is essential for assessing the adequacy of dialysis treatment.
