LOINC Code 87543-5: Beta-N-acetylhexosaminidase.A and beta-N-acetylhexosaminidase with reflex to HEXA gene panel (WBC) [Catalytic activity/Mass]

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 Beta-N-acetylhexosaminidase.A & beta-N-acetylhexosaminidase with reflex to HEXA gene panel. It is commonly used with the system or sample type WBC.

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

• Beta-N-acetylhexosaminidase.A and beta-N-acetylhexosaminidase with reflex to HEXA gene panel [Enzymatic activity/mass] - Leukocytes
• Beta-N-acetylhexosaminidase.A & beta-N-acetylhexosaminidase with reflex to HEXA gene panel
• This panel contains quantitative results for beta-hexosaminidase A (HEX A) and total beta-hexosaminidase enzymatic activity in white blood cells (leukocytes) for the carrier detection and diagnosis of Tay-Sachs disease. This test may also be ordered for carrier detection and diagnosis of Sandhoff disease, but not all positive results indicate true carriers of Sandhoff disease so follow-up molecular testing is recommended.
