Comparing measured total carbon dioxide and calculated bicarbonate.
INTRODUCTION The objective of the study is to determine the level of agreement between measured total carbon dioxide (TCO2) and calculated bicarbonate (HCO3-) in our laboratory. MATERIALS AND METHODS TCO2 and HCO3- values of 1820 samples drawn at the same time from the patient were compared. TCO2 from venous samples was measured on Dimension RxL while HCO3- was obtained from arterial blood ga...
متن کاملDiscrepancy between Measured Serum Total Carbon Dioxide Content and Bicarbonate Concentration Calculated from Arterial Blood Gases
Large differences between the concentrations of serum total carbon dioxide (TCO2) and blood gas bicarbonate (HCO3 (-)) were observed in two consecutive simultaneously drawn sets of samples of serum and arterial blood gases in a patient who presented with severe carbon dioxide retention and profound acidemia. These differences could not be explained by the effect of the high partial pressure of ...
متن کاملComparison of Directly Determined and Calculated Plasma Bicarbonate Concentration in the Turtle Chrysemys Picta Bellii at Different Temperatures
In any study on the effects of changes in body temperature on acid-base status of ectotherms, the relationship between temperature and plasma bicarbonate is of central interest. Many such studies report that arterial pH varies inversely with temperature (see reviews by Howell & Rahn, 1976; Reeves&Rahn, 1979; Jackson, 1982); in air-breathing vertebrates, this is often exclusively caused by a ris...
متن کاملTripodal transmembrane transporters for bicarbonate.
Easy-to-make tripodal tris-thiourea receptors based upon tris(2-aminoethyl)amine are capable of chloride/bicarbonate transport and as such represent a new class of bicarbonate transport agent.
متن کاملError Estimates for Calculated Glomerular Filtration Rates
Glomerular filtration rate (GFR) is a measure of kidney function. It is usually estimated from serum concentrations of cystatin C or creatinine although there has been considerable debate in the literature about (i) the best equation to use and (ii) the variability in the correlation between the concentrations of creatinine and cystatin C. The equations for GFR can be written in a general form ...
