Total CO2 Contents (TCO2) - Lab Tests Guide
May 11, 2024 · Total carbon dioxide content (TCO2) measurement is the sum of the bicarbonate, carbonic acid, and dissolved carbon dioxide (CO2) in plasma, serum or whole blood. In the peripheral venous blood this is used to assist in evaluating the pH status of the patient and to assist in evaluation of electrolytes.
tCO2 vs. pCO2: Clearing Up Confusing Terminology
Jun 4, 2018 · I’ve gotten several questions about the tCO2, pCO2, and which value is the one to use for blood gas analysis. The short answer is use the pCO2. To understand what each of these values are, and why it is so important to use the pCO2 (not …
TCO2 Blood Test Results Meaning - HRF - HRF - Health and …
If your TCO2 blood test results are higher than normal, then the most common reason for this is because of recent vomiting. Certain breathing disorders may also cause results that are higher than the normal range.
For TCO2, values measured on serum or plasma by chemistry analyzers may be slightly lower than TCO2 calculated from pH and PCO2 due to loss of CO 2 during non-anaerobic handling. 5 Up to 6mmol/L CO 2 can be lost per hour by exposure of the sample to air. 6
pCO2 (Partial Pressure of Carbon Dioxide) - Lab Tests Guide
May 8, 2024 · The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs.

Table. Imbalances and their causes; Imbalances Metabolic acidosis (serious electrolyte disorder characterized by an imbalance in the body's acid-base balance) Metabolic alkalosis Respiratory acidosis (lungs cannot remove enough of the carbon dioxide produced by the body)
tCO2 vs pCO2: Clearing up confusing terminology - YouTube
Jun 4, 2018 · Many blood gas reports and some serum biochemistry reports provide a value called the total CO2 (tCO2). While it seems you would want to use the total CO2 in...
Lab Test: Carbon Dioxide, CO2 (Blood) Level - EBM Consult
The TCO2 overestimates the plasma bicarbonate by 1-2 mmol/L. Increased levels indicate: Severe vomiting, high-volume gastric suction, aldosteronism, use of mercurial diuretics, chronic obstructive pulmonary disease (COPD), or metabolic alkalosis.
Comparative study of calculated and measured total carbon dioxide
Calculated TCO2 was obtained using blood gas analysis of pH and pCO2 in arterial whole blood on a Nova Stat Profile Critical Care Xpress analyzer. Measured TCO2 was determined using a Dimension RxL analyzer on arterial plasma, and was used as the comparative method.
TCO2: Definition, Indications, Preparation, Procedure, Results and ...
The total carbon dioxide (TCO2) blood test measures the total amount of carbon dioxide found inside the body. The normal range for carbon dioxide is 23 to 29 mEq / L (milliequivalent units per liter of blood).
