When red blood cells are seen on microscopic examination but the urine test pad is negative, it suggests that the strips are outdated, the sample was improperly mixed or centrifuged, there are too few red cells in the sediment to hemolyze, or red cells have been misidentified in the ...

The International Myeloma Working Group recommends the assessment of proteinuria in 24-h urine collection in the diagnosis of MM and periodically during treatment and monitoring of disease activity, especially because test strips do not detect monoclonal protein [105,106]. The usefulness of the spot ...
The strips were placed into the urine for 15 s, and then let sit for 5 min before reading the result to the client. As soon as the fentanyl urine test was complete, urine sam- ples were disposed of in a toilet and flushed. Clients were then invited to return for the follow-up ...
and a nonglucose oxidizing substance in the urine of cats with urethral obstruction (dipstick). Overall, the urine dipstick was found to be more accurate in cats than dogs, although false positives were more common in cats.8In dogs, the test strips had a high percentage of false-negative re...

To assess the prevalence of disseminated TB, MTB blood culture positivity was considered the gold-standard test, and the analysis was restricted to: 1. patients with at least one mycobacterial blood culture result (n = 410), to determine prevalence amongst HIV-inpatients; and 2. patients...
Currently, the most common POC method for glucose detection is enzymatic detection through electrochemical test strips utilized to measure glucose levels in blood [13]. Nonetheless, taking blood from patients is an invasive process, which presents a significant obstacle to frequent glucose monitoring [...
