What is this test?
Bromelain, also called bromelin, is a proteolytic enzyme best known as an ingredient in pineapple and bromelain supplements. This qualitative test checks a patient sample for the presence of bromelain.
Why might I need this test?
This appears to be a legacy or deprecated test and may rarely be used in current practice. It may have been ordered in a specialized clinical setting to evaluate bromelain exposure or another process associated with a specific sample type.
How is the test performed?
A laboratory examines the submitted sample using a validated method and reports whether bromelain is detected or not detected. The abbreviated test code does not clearly identify the specimen or method, so those details should be confirmed with the ordering laboratory.
How do I prepare for the test?
Preparation depends on the specimen and the instructions provided by your clinician or laboratory. Tell the healthcare team if you have recently eaten pineapple or taken a bromelain-containing supplement, because these could affect the result.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result means bromelain was detected in the sample, while a negative result means it was not detected by the laboratory method. Because this is a deprecated test with an unclear encoded specimen and method, the result should be interpreted only with the full test details and clinical context. Bromelain exposure through pineapple or supplements may be relevant when interpreting results.
Short name
