LOINC Code 89041-8: Lung cancer Ab IA [Interp]

89041-8 is a LOINC code used to identify Lung cancer Ab IA [Interp] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Lung cancer antibody. It is commonly used with the system or sample type Ser/Plas.

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 Lung cancer antibody. 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: Observation
  • Method: IA

What it does not mean

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

Key facts

Lung cancer antibody [Interpretation] in Serum or Plasma by Immunoassay
Lung cancer antibody
Screening for lung cancer using computerized tomography (CT) has been shown to decrease mortality by 20%. CT is an expensive procedure that also can reveal non-malignant changes on the chest CT. The EarlyCDT-Lung assay is a cheaper alternative with fairly good sensitivity and specificity for detecting early, asymptomatic non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). To achieve the desired specificity of 90%, the autoantibody cutoff values were chosen based on that goal. The overall sensitivity/specificity of the assay was determined to be 38%/88%. When the sensitivity and specificity were measured based on the type of tumor, NSCLC was 34%/88% and SCLC was 50%/88%.[http//cancerpreventionresearch.aacrjournals.org/content/4/7/1126.long#ref-1]
