Drawing blood is one of the most important medical procedures. It represents the basis of diagnostics and it helps establish the current health condition of a patient. If a person is performing biochemical analysis, such as determining sugar level, cholesterol, triglycerides, iron, he needs to avoid eating any food 12 hours before the procedure.
The day before drawing blood, the patient needs to eat lighter food up until 18h. After 18 o’clock, it is possible to drink liquids, except for alcohol, coffee, and sweet beverages. This is a must, given that food intake can increase the level of measured parameters. Drawing blood is also known as Venipuncture, the puncture of a vein, usually to withdraw blood.
