Homeostatic Model Assessment (HOMA) uses fasting glucose, insulin, and/or C-peptide levels. It measures how cells respond to or resist insulin, and how well the pancreas's beta cells function.
The HOMA2-IR calculation assesses the likelihood of insulin resistance and, potentially, the risk of metabolic syndrome, diabetes, and heart failure.
An elevated HOMA-IR in those with diabetes may also indicate an increased risk of complications, including cardiovascular complications. Insulin resistance may be associated with vitamin D insufficiency, which should also be assessed regularly.
