Mechanism of erroneous Dextrostix readings.

Problems in home monitoring of blood glucose.

Two hundred and forty blood glucose readings were made on 5 Glucochek machines by 2 different operators. The results on all machines correlated poorly with equivalent results from an automatic glucose analyser with major discrepancies at all glucose concentrations. There was a wide gap in performance between the 2 operators. Analysis of variance suggested that errors were not only due to inter-...

Diagnosis and treatment of hypoglycaemia in the newborn.

The importance of hypoglycaemia, defined as a true blood glucose below 20 mg./100 ml., in the newborn infant is now well recognized. It is sometimes found in the idiopathic respiratory distress syndrome (RDS), in infants of diabetic mothers, and in neonatal cold injury, and it may also occur in association with anoxia, cerebral haemorrhage, or infection (Neligan, 1965). The majority of symptoma...

Dextrostix in the detection of diabetics in general practice.

Software Techniques to Improve Data Reliability in Superconductor and Low-Resistance Measurements

Software techniques have been developed to take low-amplitude data in various patterns, assign a figure of merit to a set of data readings, edit data for erroneous readings (or other experimental variations), and to alert the experimenter if the detected errors are beyond the scope of the software. Erroneous voltage readings from digital voltmeters, intermittent electrical connections, and an a...

Blood glucose measurement with Dextrostix and new reflectance meter.

A new instrument, Eyetone, has been produced for use with a Dextrostix reagent strip for estimating blood sugar levels. It differs from the Dextrostix Reflectance Meter in having only one meter scale, a two-point calibration, and a range of measurement limited to 10-400 mg/100 ml. Results with the manufacturers' original calibration were unsatisfactory, but when recalibrated the performance of ...
