Background Chloride measurement is crucial for calculating the anion gap. Bicarbonate can
interfere with chloride measurements; however, there is no information on the specific types …

An automated analyzer for the measurement of potassium and sodium in whole blood has
been developed and evaluated. The sensors used in this instrument are the sodium glass …

Sodium and potassium were measured in sets of 102 to 107 patients sera, and in 31
commercially available control sera. The results from four routine analytical …

Bis (crown ether)-based ion-selective electrodes for sodium and potassium are described,
based on the bis [(12-crown-4)-2-ylmethyl]-2-dodecyl-2-methyl malonate sensor (I) for …

We assessed the magnitude of the errors in ionized-calcium measurements resulting from
changes in electrolyte composition for three different ion-selective electrodes: the Orion …

The comments on the one-tailed test are correct. The reason for the higher percentage
changes that they illustrate with the one-sided tests is that the false positives on the opposite …

both 20-fold diluted and undiluted, respectively, for Na and K. A separate 1-mL sample of the …

Data from the 1979 and part of the 1980 College of American Pathologists (CAP) Chemistry
Survey Program have been reviewed in order to compare the direct potentiometric …

The message of our paper has been misinterpreted. We asserted that im-munofixation(IF)
should be supported (and not replaced) by immunoelectrophoresis (IEP) for difficult cases …

Circulating sodium concentration is commonly measured by both direct and indirect ion-
sensitive electrode (ISE). We describe an unusual case with a high elevation of serum …
