The… Read More and substances essential for life. mg/dL (milligrams per deciliter) is a unit of measurement used to quantify the concentration of these substances within your blood. It’s like a measuring cup that reveals how much of a particular ingredient is dissolved in a specific volume of your “blood ocean.”

What does mg/dL Mean?

mg/dL is a composite unit that combines two measurements:

• mg (milligram): A unit of mass. Think of it as the weight of a tiny grain of sand.
• dL (deciliter): A unit of volume. It’s about 1/10th of a liter, a little less than half a cup.

So, mg/dL tells you how many milligrams (the weight) of a substance are present in a deciliter (the volume) of blood.

Etymology and History:

The metric system, from which mg/dL derives, originated in France in the late 18th centuryA century is a period of 100 years. Examples: • The 21st Century: The years 2000 to 2099. • The 19th Century: The years 1800 to 1899. • The 8th Century BC: The years 800 BC to 701 BC. Etymology: The word “century” comes from the Latin word “centuria,” which… Read More.

• Milligram (mg): The prefix “milli-” means one-thousandth, so a milligram is one-thousandth of a gram.
• Deciliter (dL): The prefix “deci-” means one-tenth, so a deciliter is one-tenth of a liter.

The combined unit, mg/dL, became widely used in medicineMedicine is the field of science and practice that deals with the prevention, diagnosis, treatment, and cure of disease. Think of it like this: • Your body is a complex machine. • Medicine is like a toolbox, and knowledge is needed to keep it running smoothly. • Doctors, nurses, and… Read More in the 20th century for reporting laboratory test results.
