LOINC Code 24318-8: Manual Differential panel (Bld)

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 Manual Differential panel. It is commonly used with the system or sample type Bld.

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: DISCOURAGED
• 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

• Manual Differential panel - Blood
• Manual Differential panel
• We have specified very few terms as required in this panel because laboratories use different approaches to reporting rarely occurring cell types and morphology findings. The terms marked as C (conditional) must be included in the panel if the count for that cell type is non zero. However, it is expected that all observed and clinically important cell types and morphology findings will be included in the manual differential count panel. The Panel provides optional ways of reporting special findings. Morphology findings can be reported as ordinals-e.g rare, few, many - via the discrete LOINC codes provided, or as simple list of the findings seen (via the morphology nominal LOINC terms)
