Understanding Hypoglycemia Labs: Tests for Diagnosing Low Blood Sugar

Hypoglycemia is a condition in which blood sugar levels drop below normal levels. This can lead to symptoms such as confusion, dizziness, and weakness. If left untreated, hypoglycemia can be dangerous and even life-threatening. In this article, we'll explore the different laboratory tests that can be used to diagnose hypoglycemia and monitor blood sugar levels.

Blood Glucose Test

The most common laboratory test for hypoglycemia is a blood glucose test. This test measures the amount of glucose (sugar) in the blood at a given time. Normally, blood glucose levels should be between 70 and 99 mg/dL (milligrams per deciliter) when fasting, and less than 140 mg/dL two hours after eating.

If blood glucose levels are consistently below 70 mg/dL, a diagnosis of hypoglycemia may be made. However, it is important to note that blood glucose levels can fluctuate throughout the day, and a single low reading may not necessarily indicate hypoglycemia.

Continuous Glucose Monitoring (CGM)

Continuous glucose monitoring (CGM) is a newer technology that allows for continuous monitoring of blood glucose levels over a period of time. This involves wearing a small sensor on the skin that measures glucose levels in the interstitial fluid (the fluid between cells).

CGM can be particularly useful for people with diabetes who are at risk for hypoglycemia, as it can provide real-time information about blood sugar levels and alert the wearer if levels are too low. CGM can also be used to
