There used to be a similar problem with glucose, with 1+ on Roche being different to 1+ on Multistix, not sure if this is still the case but probably is. Would be nice if a compromise could be found, so at least 1+ meant the same. However it might mean that changing from one manufacturer to another was easier, so unlikely to happen! Tim. ________________________________ From: Clinical biochemistry discussion list on behalf of Richard Stott Sent: Wed 4/30/2008 3:43 PM To: [log in to unmask] Subject: POCT urine screening[Scanned] We are in the process of implementing a new contract for urine dipsticks which involves laboratory control of QC and EQA for the first time. This involves a move away from the "Multistix" style of reporting and so far we have one hospital site using the new sticks with the only problems coming from the Womens' hospital. They were using the plusses associated with a urine protein concentration of 300mg/dl as a contributory trigger to admission and potential induction of labour in pre-eclampsia situations. That particular level is not present as a reference point on the packaging of the new strips (150 and 500 mg/dl) so the nurses and midwives are wanting to stay with the previous sticks. They didn't spot the cut-off issue when they came to the evaluation sessions and we did not anticipate them using urine dipsticks as a diagnostic test. The meter does not give readings between the concentrations on the packaging either. I have explained the potential folly of making decisions based on a guestimate of urine protein concentration rather than protein/creatinine ratio and am waiting for a decision. It seems that about half of the UK sales go to Roche or other suppliers with the same interpretation levels so others may have experienced the same issues. I am looking for guidelines or protocols from hospitals which already use this type of strips in the hope we can change to a more scientifically based practice. Thanks in anticipation.
