Buffered Base (BB)

Buffer base (BB) is the sum of the buffering bases in the blood, including HCO3-, HPO4-, hemoglobin, and plasma proteins. BB can reflect the body's overall buffering capacity for acid-base balance disorders, it is not affected by respiratory factors and carbon dioxide changes. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Tips: Some drugs can affect the pH of the blood. The doctor should inform the doctor about the recent medication before the test. Normal value 45 ~ 55mmol / L, the average value of 50mmol / L. Clinical significance Increased is common in metabolic alkalosis. Reduction is common in metabolic acidosis. If the actual bicarbonate (AB) is normal at this time, it may be anemia or low plasma protein. Low results may be diseases: high metabolic acidosis results may be diseases: metabolic alkalosis precautions 1. Conventional arterial blood should be taken for examination. The femoral artery is often taken and the brachial artery blood is sent for examination. If venous blood is to be taken, the forearm should be immersed in warm water of 45 ° C for 20 minutes to make the venous blood arterial. It is not advisable to use a tourniquet when drawing blood. 2. Flush with heparin beforehand in the syringe. 3. Ensure that the needle and needle of the syringe are tightly combined, and there must be no air leakage to ensure that the blood sample does not come into contact with the outside air. 4. After the blood is drawn, the time for pressing the needle is longer to prevent congestion and timely send the specimen. 5. Some drugs may affect the pH of the blood, and the doctor should be informed of the recent medication before the test. 6. Before taking blood, please indicate whether oxygen is taken. The blood specimen should be isolated from the outside air and sent to the test in time. 7. The use of certain drugs can increase or decrease the pH of the blood, such as the use of sodium bicarbonate, ethenic acid, sodium glutamate, phenylbutazone, aspirin, etc. to increase blood pH; use tetracycline, isoniazid , phenformin, ammonium chloride can reduce blood pH. Inspection process Same electrode assay. Not suitable for the crowd No taboos. Adverse reactions and risks Discomfort: There may be pain, swelling, tenderness, and visible subcutaneous ecchymosis at the puncture site.
