What is the main purpose of blood sugar testing?

The primary purpose of blood sugar testing is to identify the amount of sugar circulating in the blood. This measurement is crucial for individuals, particularly those with diabetes, as it helps to manage their condition effectively. By knowing the blood sugar levels, healthcare providers and patients can determine how much insulin is necessary or if other interventions are required to maintain optimal blood glucose levels. Proper management of blood sugar is vital in preventing complications associated with high or low glucose levels.

While determining the type of insulin needed is important, it is contingent upon knowing the current blood sugar levels and individual factors. Kidney function and blood pressure are unrelated to blood sugar testing, as these parameters require different assessments and tests to evaluate overall health.
