Primary care clinics can often perform basic metabolic screening such as fasting glucose, HbA1c, and standard biochemistry panels. However, assessing “insulin resistance” typically requires fasting insulin and a HOMA-IR calculation, and availability can vary by clinic and laboratory access. The most practical pathway is to start with primary care screening, and if risk is identified, proceed with internal medicine or endocrinology referral for a more comprehensive work-up. Waist circumference, blood pressure monitoring, and a lipid profile are also powerful risk indicators at the primary care level. In short: primary care is a strong entry point; specialist evaluation is the next step when deeper assessment is required.
