LOINC Code 74773-3: Immunoglobulin light chains and heavy chains panel

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Immunoglobulin light chains & heavy chains panel. It is commonly used with the system or sample type Ser/Plas.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Order
• Panel type: Panel

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Immunoglobulin light chains and heavy chains panel - Serum or Plasma
• Immunoglobulin light chains & heavy chains panel
• Immunoglobulins are made up of two identical heavy chains which define the immunoglobulin class (A, G, or M) and two identical light chains, kappa or lambda (κ or λ). Each light chain is bound to a heavy chain. This assay quantitates the absolute value of the IgMκ, IgMλ , IgGκ, IgGλ, IgAκ and IgAλ separately, along with their ratios (IgMκ/IgMλ, IgGκ/IgGλ, and IgAκ/IgAλ ).
