Background It is sometimes necessary for the laboratory to re‐test samples for critical serum
electrolyte levels. It is important to assure reproducibility of results when testing is performed …

An automated analyzer, in which ion-selective electrodes are used to measure sodium,
potassium, and chloride in serum, was assessed in a clinical setting. Day-to-day precision …

The determination of electrolytes in the clinical laboratories is carried out in samples of
serum or plasma in situations that tubes remain open during a lingering time. Objective: to …

[Agreement in the determination of electrolytes in samples of serum and plasma. Stability of
these samples kept for 2 hours at room temperature with uncovered tubes]. - Abstract - Europe …

The widespread use of ion-selective electrode causes the reference range of the anion gap
(AG) to be lowered from 8–16 to 3–11 mmol/l. The use of the outdated reference range (8 …

Three interlaboratory round-robin studies (RR1, RR2, and RR3) were conducted to identify a
serum-based reference material that would aid in the standardization of direct ion-selective …

Background Electrolytes are measured regularly in a variety of clinical settings because
electrolyte imbalance can be life‐threatening. Although arterial blood‐gas analysis reports …

We determined serum Na+ and Cl− results using Technicon's Flame IV-Auto Analyzer II
(FLIV/AAII) system and Kodak's Ektachem 400 clinical analyzer. Our objective was to …

Electrolytes for sodium, potassium, magnesium, and calcium are important serum ions that
are frequently assayed in clinical laboratories. In this study, we assessed the trueness of …

The International Federation of Clinical Chemistry (FCC) and the National Committee for
Clinical Laboratory Standards (NCCLS) are about to recommend to adjust sodium and …
