97543-3Bicarbonate [Moles/volume] in Central venous bloodActive

Part Descriptions

LP15441-6   Bicarbonate
Bicarbonate is an electrolyte and typically measured along with other electrolytes (e.g. sodium, potassium, and chloride) to detect, evaluate, and monitor electrolyte imbalances. Low bicarbonate levels may occur in patients with Addison's disease, chronic diarrhea, diabetic ketoacidosis, and kidney disease. Increased levels may be seen in patients with severe vomiting, cushing syndrome, and metabolic alkalosis. Various drugs may also increase or decrease biocarbonate levels.[Lab Tests Online: co2]
Bicarbonate and total CO2 are not synonyms. Total CO2 = bicarbonate + CO2 + carbonic acid. Under normal circumstances, bicarbonate is the primary constituent of total CO2, however, in certain pathologic conditions, CO2 and/or carbonic acid contribute a clinically significant fraction of the total.

LP422982-1   BldCV
Central venous blood is blood found in the interior jugular or subclavian vein sampled via a central venous catheter. The composition of central venous blood is different from mixed venous blood, found in the pulmonary artery and also sampled via catheter, and peripheral venous blood, sampled via venipuncture. Central venous blood contains blood from the upper body, whereas mixed venous blood contains deoxygenated blood from the entire body. Source: LOINC
