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 HTLV I & II 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
• Method: IB

What it does not mean

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

Key facts

• HTLV I and II panel - Serum or Plasma by Immunoblot
• HTLV I & II panel
• This is a confirmatory panel for the detection and discrimination of antibodies against human T-cell lymphotropic virus type I (HTLV-I) and type II (HTLV-II). Two gag (p19 I/II, p24 I/II) and two env (gp46 I/II, gp21 I/II) bands are applied as non-type- specific antigens, which confirm the presence of antibodies against HTLV I and II. The type-specific antigens for HTLV-I (gag p19-I, env gp46-I) and for HTLV-II (env gp46-II), are applied to differentiate between HTLV-I and HTLV-II infections. Streptavidin is used as a negative control. This panel was created for the submitter's INNO-LIA HTLV I/II Score test kit.
