A new reagent strip has been developed for measuring phenytoin in serum or plasma. It utilizes the chemistry of the Apoenzyme Reactivation Immunoassay System (ARIS) and is designed for use with the Seralyzer reflectance photometer. The 90-s test relies on comparison of strip reactivities with a two-point calibration line, which can be validly stored in the instrument for two weeks. Within-run C...

A 78-year-old male patient who had an indwelling urinary catheter because of benign hyperplasia of the prostate and who had been receiving hemodialysis twice a week due to endstage renal disease was admitted to our hospital complaining of three days of purple urine color (Figure 1). His medications included beta blocker, anti-aggregant, erythropoietin, piracetam and calcitriol therapies. A urin...

1. A review is presented of the literature on riparian vegetated buffCT strips (VBS) for use in stream-water-quality restoration and limitations associated with their use are discussed. The results are also presented of recent investigations on the effectiveness of a forested and a grass vegetated buffer strip for reducing shallow subsurface inputs of nutrients from agriculture to a stream in c...

Urinalysis as a simple, non invasive and inexpensive laboratory test remains to be the cornerstone tool in the assessment of the urinary system. It can be easily used for screening of kidney diseases. Previously many screening programs using urinalysis have been carried out using reagent strips testing, and their effectiveness in evaluating kidney disorders with relatively low costs [1,2]. Mass...

Point of Care Testing (POCT) improves clinical process outcome. It has the potential to reduce errors and the wastage of resources. There is a significant amount of information obtained through the examination of urine. The routine urinalysis consists of two major components: physiochemical determination and microscopic examination of urine sediment. The physiochemical determination includes th...

An 83-year-old woman presented to the emergency department with weakness and weight loss. A urinalysis was ordered. The urine was clear and light yellow. A urine protein estimate obtained with reagent strips (Clinitek Atlas ; Siemens) was 30 mg/dL; however, quantitative measurement of the total protein concentration (UniCel DxC 800; Beckman Coulter) of a second urine sample yielded a value of 9...

Rapid diagnostic tests are needed for the implementation and monitoring of national schistosomiasis control programmes. The field applicability of the circulating cathodic antigen (CCA) urine reagent strip for the diagnosis of Schistosoma haematobium infection was evaluated among 265 pre- and primary schoolchildren aged 2-19 years in a rural area of Zimbabwe. The CCA strip was compared with egg...

The use of reagent strips to monitor blood glucose concentrations via glucose meters in diabetic patients is gaining popularity mainly due to their favourable performance as compared to the autoanalyser methods. As part of a programme of extra laboratory tests, such estimations were performed at a medical nursing station and results compared with simultaneous estimations in the clinical laborat...

BACKGROUND Urinary screening tests for early detection of renal diseases in asymptomatic school children and adolescents are important in the detection of silent renal diseases. OBJECTIVES The purpose of the study was to determine the prevalence of occult renal diseases by dipstick test (reagent strips) in asymptomatic Nepalese children. PATIENTS AND METHODS A total of 2,243 school children...
