Urinary Leukotriene E4 in Asthma

In Asthma, published studies report higher levels of Urinary Leukotriene E4 than in healthy volunteers. The source does not tie this marker to a specific symptom cluster, so it is best read as a biological signal rather than a symptom predictor. This entry summarises Suzuki et al. 2000. Group-level associations like this do not translate into an individual diagnostic cut-off.

Frequently asked questions

Is Urinary Leukotriene E4 high or low in Asthma?

Elevated. Studies summarised in the OSMF atlas report higher Urinary Leukotriene E4 in Asthma than in healthy volunteers. Source: Suzuki et al. 2000.

Which test measures Urinary Leukotriene E4?

The atlas record does not list a standardised clinical test code (LOINC) for Urinary Leukotriene E4, which usually means it was measured with research assays or study-specific protocols rather than a routine clinical panel. Check the cited source for the exact method.

Is one abnormal Urinary Leukotriene E4 result diagnostic of Asthma?

No. No single biomarker is diagnostic of Asthma. Urinary Leukotriene E4 findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
