Lab Tests for Type 2 Diabetes
Type 2 diabetes affects over 37 million Americans and occurs when your body becomes resistant to insulin or doesn't produce enough to maintain normal blood sugar levels. Regular lab monitoring is essential for diagnosing prediabetes, managing diabetes, and preventing complications like heart disease, kidney damage, and nerve problems. Key tests include HbA1c for long-term blood sugar control, fasting glucose for current levels, and fasting insulin to assess insulin resistance. JustLabs lets you order these tests online at self-pay prices — no doctor visit required.
