Description

I am unable to find laboratory results for beta-d-glucan despite the test being mentioned in notes/radiology reports. I've tried searching across all dim tables using various case-insensitive representations (e.g. %beta-d-glucan%, %bdg%, %glucan%, etc) with no luck. I've also tried searching using the brand name Fungitell. Searching hosp.d_labitems using where lower(label) like '%beta%' does return the following:

which has several results for Beta however I'm unsure if this is referring to Beta Hydroxybutyrate or some other laboratory test.

Any suggestions/explanations would be greatly appreciated!
