Assessment of urine specific gravity by reagent strip test in newborn infants.

Specific gravity was measured with a strip test (N-Labstix SG, Ames Division, Miles, Puteaux, France) in 98 urine specimens obtained from 57 newborn infants; osmolality was measured with an osmometer. The strip test did not accurately predict urine osmolalities; a very weak correlation was found between the specific gravity and the osmolality (r2 = 0.598, P < 0.01). Specific gravity values up to 1.015 always indicated hypotonic urine with osmolality less than 211 mosmol/kg H2O, whereas higher values could be associated with either hypotonic or hypertonic urine. Therefore, the strip test cannot be recommended in the neonatal period because its clinical usefulness is strictly restricted to urine samples with low specific gravities (< or = 1.015) and without confounding variables (urine pH > or = 6.5, glucosuria, proteinuria, haematuria).

[Optimizing the use of reagent strips by type 2 diabetics].

What is considered to be the best metabolic self-control method among diabetic patients is to practice capillary glycemia. Nonetheless, the inappropriate use of reactive strips leads to an increase in expenses without preventing complications. Therefore, the authors want to find out if patients make an appropriate use of these strips; to evaluate whether or not a health education training program optimises their use and if it improves metabolic control; and to check to see if their effects last over time when patients stop using them. As a result, the authors carried out a longitudinal intervention study without a random selection; this study was carried out in a urban primary health care unit. The subjects were 267 type 2 diabetes sufferers who were under pharmaceutical treatment and a self-control method. There were 3 periods to compare the use of strips and metabolic control methods: 1) initial consumption level measurement during which reactive strips were dispensed upon demand, 2) dispensing strips after some health education training program, and 3) dispensing strips without any educational training program. The authors conclude that the health education training program carried out by nurses is effective because it optimises the consumption of reactive strips while maintaining a stable metabolic control. The authors presenting their findings orally at the 10th "FEAED" National Congress.

Stability of reacted reagent strips (Chemstrips) for blood glucose determinations.

Reacted Chemstrips were placed in an unsealed envelope or in desiccator vials which were opened daily after 1, 2, 3, 4, 5, 6, 7, and 14 days. The time of change of the reading for 2 days in a row by all three observers was noted. Readings in the low and normal range were most stable and can be considered reliable for 2-3 days when protected from light. If in a desiccator tube, the strips can be reliably reread when the tube is opened as long as 7 days later. In a separate study, strips were left exposed on the laboratory bench or placed in a vial and read frequently for 6 h and again at 28 h. This exposure, comparable to the CS being taped to a hospital record, results in reading changes as early as 2 h after reaction.

Quantitative urine culture by reagent strip incubation.

The filter paper culture-tetrazolium test ressults have been compared with routine hospital streak plate cultures in 400 random urine specimens. Pseudomonas cultures tended to impart a color change to the test pads which rendered interpretation difficult. While a consistently accurate quantitative interpretation of these cultures did emerge during the course of the trial studies, some degree of observer accommodation and bias, in terms of the manufacturer's instructions and description, was necessary to achieve an appropriate reading. When the hospital laboratory results and culture strip test results are compared in terms of colony counts greater than 10-4 bacteria per milliliter and less than 10-4 bacteria per milliliter, the method was found to be 93% sensitive for the total count and 83% sensitive for the gram-negative count with a specificity correlation of 96% for the total and gram-negative counts, respectively.

[Urinary tract infections in newborns: sensitivity, specificity, and predictive value of urinary screening with the reagent strip test].

Important considerations in evaluating newborn urine examinations by dip-stick method are: ease of performance, the volume of the specimen required for test, the time required to perform the test and the cost. In considering the dip-stick test for the early diagnosis of Urinary Tract Infections (U.T.I.), it has never been tested with later follow-up to evaluate its sensitivity and specificity, also in regard to reduce the risk of further complications for urinary tract and kidney.

[Value of reagent strips in screening urinary infection in children].

The aim of this study is to specify the role of rapid tests in the screening of childhood urinary tract infection. During the period between july to december 1998, 572 urinary samples were collected from pediatric out-patient in Hôpital d'Enfants de Tunis and aged from 1 month to 15 years. Only 75 samples (12.5%) were culture positive. The predictive value of leucocytes or nitrites test was 97.2%. These results allowed the use of rapid test in the screening of urinary tract infection in children. However, if clinical symptoms are present, the culture of urine must be associated to the rapid test.

1991 Federal Nursing Service Award recipient. The effect of increased atmospheric pressure on glucose reagent strip accuracy.

Hyperbaric oxygen (HBO) is currently being used throughout the world as an adjunctive therapy for non-healing diabetic wounds. Anecdotal accounts of diabetic patients experiencing hypoglycemic reactions with HBO necessitated glucose testing by fingerstick during treatment dives to 2.4 atmospheres absolute. This study looked at four glucose testing methods and the accuracy of their readings using high and low control solutions at both sea level and at depth. A one-way analysis of variance showed significant differences with all of the high and 75% of the low control solutions when comparing sea level readings to depth readings. The significance varied between reaction rate and end point reading methods, with the reaction rate technology performing better.
