The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations.
There are several ways to measure glycated hemoglobin, of which HbA1c (or simply A1c) is a standard single test. [5] HbA1c is measured primarily to determine the three-month average blood sugar level and is used as a standard diagnostic test for evaluating the risk of complications of diabetes and as an assessment of glycemic control .
HCPCS includes three levels of codes: Level I consists of the American Medical Association's Current Procedural Terminology (CPT) and is numeric.; Level II codes are alphanumeric and primarily include non-physician services such as ambulance services and prosthetic devices, and represent items and supplies and non-physician services, not covered by CPT-4 codes (Level I).

Logical Observation Identifiers Names and Codes (LOINC) is a database and universal standard for identifying medical laboratory observations. First developed in 1994, it was created and is maintained by the Regenstrief Institute , a US nonprofit medical research organization.
Chronic hyperglycemia can be measured via the HbA1c test. The definition of acute hyperglycemia varies by study, with mmol/L levels from 8 to 15 (mg/dL levels from 144 to 270). [48] Defects in insulin secretion, insulin action, or both, results in hyperglycemia. [16]
On average, each change of 3.3 mmol (60 mg/dL) in average blood sugar levels will give rise to changes of 2% HbA1c and 75 μmol fructosamine values. [6] However, this overemphasizes the upper limit of many laboratories' reference ranges of 285 μmol/L as equivalent to HbA1c 7.5% rather than 6.5%.
