Low albumin may be a sign of not eating enough protein, kidney problems, liver disease, heart disease, or some types of cancer. The most common cause of a low anion gap is a low level of albumin, a protein in the blood. But this result is so rare that your provider will usually have you tested again to make sure the results are accurate.

Acidosis may be caused by:Ī low anion gap test result may mean you have alkalosis (blood that is less acidic than normal). Your provider will use the results of the anion gap test, your medical history, and other tests to make a diagnosis.Ī high anion gap test result may mean that you may have acidosis (blood that is more acidic than normal). This device was concluded to have potential for providing faster results and relatively acceptable values to clinicians in need of immediate results.Several types of medical conditions can cause abnormal anion gap test results. ultaneous blood measurements of sodium, potassium.

A very high correlation was observed in glucose, blood urea nitrogen and creatinine ( R>0.975), high correlation was observed in sodium, potassium, Hct and Hb ( R>0.9), and relatively good correlation was observed in chloride and total carbon dioxide ( R>0.7) compared to the central laboratory analysers.Ĭonclusions: i-STAT showed relatively high precision and linearity, and comparable data to that of routine hematology and chemistry analysers. ABSTRACT: The performance of the i-STAT portable clinical analyser for measuring. In the aspect of linearity, the correlation coefficient values of all analytes were over 0.975 in the clinically important concentration range. Results: The coefficient of variation values for the within-run precision and total precision at 3 levels of all analytes were within 5%, except those for low level creatinine. Comparisons with a central laboratory hematology analyser, Coulter LH 780 (Beckman Coulter Inc., USA), and a chemical analyser, UniCel DxC 880i (Beckman Coulter Inc.), were performed using 85 patient samples according to CLSI EP9-A3. Methods: The precision and linearity of the 10 analytes were measured according to Clinical and Laboratory Standards Institute (CLSI) EP15-A3 and EP6-A guidelines. Therefore, the aim of this study was to evaluate the performance of the i-STAT POC analyser (Abbott Diagnostics, USA) for testing 8 chemical analytes (viz., sodium, potassium, chloride, total carbon dioxide, blood urea nitrogen, creatinine, glucose, and ionised calcium) and 2 hematological analytes (hematocrit, hemoglobin ). The demand for POCT in the medical field is expanding significantly, given that rapid results can eventually lead to early diagnosis and immediate clinical management of diseases. Background: Point-of-care testing (POCT) is designed to be used near the site where the clinical care is being delivered.
