Monkeypox ELR data

Hi everyone,

Just a quick question regarding MPOX ELR data. How complete are they in terms of getting results as required to your jurisdictions from all testing labs?  Any data quality issues of note?  Thank you so much!

Annie, we're getting reasonably complete data -  with the proviso that Quest is not sending specimen source. We're getting either "Unknown source" or an empty field. Quest says there is no source option available for specimen submissions for MPX. Is anyone else seeing this?

Hi Annie,
Lab results are pretty complete for person information - I can't comment on race/ethnicity as I'm looking at data after it is put into our surveillance system and these cases have a lot of daily cleaning. The TAT from our small number of positive results (125) is best for our State Lab (0-2 days); Commercial labs are 3-7 days; CDC is 14+days. Ordering facility seems to be pretty complete. 

Agree with Sita - I've already asked Quest about specimen source being "unspecified" and can that be corrected. Since the majority of testing is being done from lesion swabs, I would expect at least the source to be 'lesion swab'. But we've had this issue before.

We (NH) are getting 'Unspecified source' from Quest. ARUP is not sending specimen source either. Quest Chantilly is sending ELR with missing LOINCs in OBX-3. Several other states reported this as well and Quest is working to correct. The rest of the data from the labs seems mostly complete except race/ethnicity which is missing/unknown in majority of MPV ELRs (Quest hasn't sent any ELR to us with completed race/ethnicity). We haven't received any ELR from Aegis or Sonic yet so can't comment on their data quality.

So has ARUP been validated? We've gotten some tests in and now have a positive so want to make sure this test is good to go. Thanks.

ARUP indicated their test is based on the same assay as the CDC's and "The FDA has declared enforcement discretion and will not require LDTs for monkeypox to be submitted to the FDA". All their FAQs are available at this site: https://www.aruplab.com/monkeypox-testing#faq.

One caveat is that ARUP's assay can technically detect variola virus, so it is slightly different than CDC's assay. This is why ARUP is using LOINC 41853-3 (Orthopoxvirus DNA [Presence] in Specimen by NAA with probe detection) while labs performing the CDC-based non-variola orthopoxvirus assay are using LOINC 100434-0 (Orthopoxvirus.non-variola DNA [Presence] in Specimen by NAA with probe detection). See the 'Note' section at this site: https://ltd.aruplab.com/Tests/Pub/3005716?_ga=2.193480109.1847909300.1661350086-79830901.1660139529
