About this test

The Glucose blood test measures the amount of sugar (glucose) in your blood at the time of collection, offering a direct snapshot of how your body is processing its primary energy source. Glucose fuels your cells, especially the brain, and maintaining balanced levels is essential for overall health, energy, and metabolic function.  We will Screen for normal, low, or elevated blood sugar levels and identify prediabetes or diabetes and detect hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar). Please fast 8 hours before the test.

Fasting Insulin

The Fasting Insulin test measures the level of insulin in your blood after a period of fasting, offering critical insight into how efficiently your body uses insulin. Elevated fasting insulin levels can signal insulin resistance, often years before blood sugar levels rise, making this test a powerful early indicator of metabolic dysfunction.  This test measures fasting insulin levels to evaluate how much insulin your body must produce to maintain normal blood sugar. Please fast 8 hours before this test.
