DL full form in medical term is Decilitre, or it is also called Grams (gm) per Decilitre (dL). In the human body, the haemoglobin level is indicated as the amount of hemoglobin in gm/grams per Decilitre of whole blood, a DL being 100 mL (milliliters). Depending on the gender of the person, starting in adolescence and age, the normal ranges for hemoglobin vary. As per the American Diabetes Association, MG/DL means mg per decilitre. It is a unit of measure that indicates the deliberation of a substance in a certain amount of fluid. The blood glucose test results in the United States of America are stated as mg/dL.
DL also refers to direct Laryngoscopy. Laryngoscopy is a procedure performed to check the voice box, larynx, or throat using a small device.
Your healthcare provider can perform this to check out when you have a sore throat or to diagnose ongoing issues such as bad breath, hoarseness, or coughing. In direct laryngoscopy (DL), the healthcare provider uses a small instrument to push the tongue down and move the epiglottis. He may do this to eliminate tissue samples for testing or small growths.
