hydrogen carbonate has been researched along with Sensitivity and Specificity in 96 studies
Bicarbonates: Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
hydrogencarbonate : The carbon oxoanion resulting from the removal of a proton from carbonic acid.
Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)

Healthy controls underwent 3D MRE on a 1.5T scanner. Regions of interest for measurement of pancreatic stiffness were drawn by two blinded readers and statistical analysis were performed for comparisons between the 2 groups. (NCT02869893)

"Participants underwent MR imaging prior to and following secretin administration. Pre-secretin imaging lasts approximately 20 minutes. Post-secretin images were acquired at 1 minute, 5 minutes and 15 minutes following completion of secretin injection. Pre-secretin enteric fluid volumes were subtracted from post-secretin enteric fluid volumes for each participant to determine volume secreted in response to secretin administration at each time point.~A commercially available software package determines the area of fluid signal on the MR images. The fluid signal from the pre-secretin images is then subtracted from the each post-secretin image (1, 5 and 15 minutes images) to determine the amount of fluid produced by the introduction of secretin."
