Quick Facts
- Sample: Blood
- Fasting: Fasting for at least 12 hours is required
- Turnaround: 1-2 business days. May take longer based on weather, holiday, or lab delays.
What This Test Measures
This test combines three components: a Comprehensive Metabolic Panel (CMP-14) with eGFR, a Hemoglobin A1c test, and a CBC with Differential and Platelets. The CMP-14 includes a current glucose measurement, along with kidney markers (BUN, creatinine, BUN/creatinine ratio, eGFR), liver markers (total protein, albumin, globulin, albumin/globulin ratio, bilirubin, alkaline phosphatase, AST, ALT), electrolytes (sodium, potassium, chloride, total carbon dioxide), and calcium.
The Hemoglobin A1c component is a separate, percentage-based measurement that reflects average blood glucose exposure over roughly the past 2 to 3 months, distinct from the same-day glucose value captured in the CMP-14. The CBC with Differential and Platelets reports red blood cell, white blood cell, and platelet values, along with the five-part white cell differential and calculated indices such as MCH, MCHC, MCV, and RDW. Each component provides a different type of information, and no single value within this test offers a complete picture of diabetes status on its own.
Benefits
- Provides a current glucose reading alongside longer-term A1c context
- Offers kidney and liver function markers relevant to diabetes management
- Includes electrolyte and calcium values for broader health context
- Adds CBC data to support monitoring of overall blood health
- Supports ongoing tracking of glycemic status over time
Who Is This Test For?
- People managing an existing diabetes diagnosis who track glucose and A1c
- Individuals whose healthcare provider recommends kidney and liver monitoring
- People wanting a broader snapshot of metabolic and blood health markers
- Individuals following up on previous glucose or A1c results
- People whose provider wants combined glycemic and organ function data

FAQ
1. Do I need to fast or prepare for this test?
Fasting for at least 12 hours is required before this test. No additional preparation instructions are provided beyond this fasting window.
2. How quickly will I get results?
Results are generally available within 1-2 days of your sample being processed. Weather, holidays, or lab-specific delays may extend this timeframe.
3. What can my results tell me?
Because this test bundles several components, your results can show a current glucose value, a 2 to 3 month average glycemic picture from A1c, kidney and liver function markers, electrolyte and calcium levels, and CBC values. Each section reflects a different aspect of your health, so a change in one marker does not explain the others, and the combined results are best reviewed together with a provider.
4. What factors can affect my results?
Not fasting for the full 12 hours before your blood draw can affect glucose, lipid-related, and other CMP-14 values. Hydration status can influence BUN, creatinine, and the BUN/creatinine ratio. Recent illness, inflammation, or blood loss can affect CBC values such as white blood cell count or hemoglobin. The source does not list additional factors such as medications or supplements.
5. How do I interpret the results?
Interpreting this test involves looking at each component in the context of its own reference range and your personal health history, since glucose, A1c, kidney, liver, electrolyte, and CBC values each measure something different. A single elevated or low value, on its own, does not confirm or rule out diabetes or another condition. Reviewing the full set of results with a qualified healthcare provider helps place each marker in proper context.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
6. What should I do if my results are abnormal?
An out-of-range result on any part of this test is worth discussing with a qualified healthcare provider rather than interpreting on your own. Your provider can determine whether additional evaluation, repeat testing, or further workup makes sense based on your full health picture. This test does not diagnose diabetes or any other condition on its own, and no treatment changes should be made based on these results alone.
Pre-test preparation
Fasting for at least 12 hours is required before this test. No additional preparation instructions, such as dietary restrictions, medication guidance, or activity limitations, are provided in the source.
