A baseline laboratory panel is the set of measurements taken before an intervention begins, so that measurements taken later have something to be compared against. Its value lies in the comparison rather than in any individual value.[1]
The principle that makes a baseline useful is consistency: the same analytes, on the same assay platform, under the same collection conditions. A follow-up measurement from a different laboratory may differ from the baseline by more than the intervention changed it. See Fasting insulin for the clearest example of between-assay variation.[2]
The panels discussed in this field typically span glycaemic markers, a lipid panel, hepatic and renal function, and thyroid function, with additions according to the question being asked.[1]
Common components
[edit]| Domain | Typical analytes |
|---|---|
| Glycaemic | Haemoglobin A1c, fasting glucose, Fasting insulin |
| Lipid | Lipid panel, Apolipoprotein B where available |
| Hepatic | Alanine transaminase, Gamma-glutamyl transferase |
| Renal | Creatinine with eGFR, Urine albumin-to-creatinine ratio |
| Thyroid | Thyroid function test |
| Other | Vitamin B12 status, High-sensitivity C-reactive protein |
The table lists analytes that appear in the literature and in the panels people discuss; it is not a recommendation, and which measurements are appropriate for any individual is a clinical question this wiki does not answer.[1]
Derived indices such as HOMA-IR are computed from panel components rather than measured, and inherit the properties of their inputs.[2]
