RBS

Description

  • < 80 -160 mg/dl

Clinical significance

  • A random blood Glucose checks your glucose at any random time of the day. Glucose is the primary source for the body’s cells and the only energy source for brain and nervous system. During digestion dietary sources are broken down into glucose .Using glucose for energy production depends on Insulin, a hormone produced by the pancreas. 
  • Normally blood glucose rises slightly after a meal and insulin is released by the pancreas in response. As glucose moves into the cells and is metabolized, the level in the blood drops and the pancreas responds by slowing, then stopping the release of Insulin.
  • If the blood glucose levels drops too low, such as might occur in between meals or after a strenuous workout, glucagon ( another pancreatic hormone) is secreted to induce the liver to turn some glycogen back into Glucose, raising the blood glucose level. If the glucose/insulin feedback mechanism is proper, the amount of glucose in the blood remains stable.
