Bicarbonate

Definition

Bicarbonate is a negatively charged ion (HCO3-) that plays a crucial role in maintaining the body's acid-base balance. It is produced by the kidneys and helps neutralize acids in the blood.

5 Must Know Facts For Your Next Test

1. Bicarbonate levels are a key indicator of renal function and acid-base status.
2. The normal range for bicarbonate in blood is typically between 22-28 mEq/L.
3. Low bicarbonate levels can indicate metabolic acidosis, often seen in patients with chronic kidney disease.
4. Bicarbonate supplementation may be necessary for patients with renal disease to manage acidosis.
5. Dietary intake of bicarbonate-rich foods, like fruits and vegetables, can help support healthy bicarbonate levels.
