Type 1 diabetes, relatively easy to diagnose, presents with several symptoms and diagnostic methods. Primary methods used in diagnosing type 1 diabetes include blood tests, blood sugar tests, and urine tests. These include:

**Blood Sugar Test:** This test checks the amount of sugar in the blood. Patients are required to fast before the test. A very high blood sugar level indicates type 1 diabetes.

**Glycosylated Hemoglobin Test (A1c):** If blood sugar tests suggest type 1 diabetes, the A1c test measures a person's average blood sugar over three months.

**Antibody Test:** This test detects autoantibodies in the body to help determine the presence of type 1 or type 2 diabetes. Certain autoantibodies, which are proteins that mistakenly attack the body's own tissues, are indicative of type 1 diabetes. These autoantibodies are typically not found in people with type 2 diabetes.

**Urine Test:** In diagnosing type 1 diabetes, a urine test is used to detect ketones in the body, rather than glucose. High levels of ketones can make the blood more acidic, negatively impacting a person's health.

**Arterial Blood Gas:** This test measures the levels of oxygen and carbon dioxide in the blood. A sample is taken from an artery.
