Mpox Virus Qualitative PCR
General Information
Lab Name
Mpox Virus Qualitative PCR
Lab Code
MPXQLT
Epic Name
Mpox Virus Qualitative PCR
Description
The detection of mpox virus DNA by real-time PCR amplification. The primers used in this PCR reaction amplify the F3L gene (Maksyutov et al., J Virological Methods 2016) and the probe hybridizes the target sequences between the primers that specifically identifies the PCR amplicon. The minimum virus level that gives a positive result in 95% of replicates is 328 copies/mL in either VTM/UTM or Aptima multitest tubes.

Guidelines
Ordering & Collection
Specimen Type
Collection
Acceptable Sample Types: Swabs in VTM (viral transport media) or UTM (universal transport media) or Aptima Multitest Swab Transport Media or Dry Swabs
- Preferred Specimen Type: Swabs of skin lesion (LESION/PUSTULE/VESICLE/RECTAL/GENITAL) in VTM/UTM
- Alternative Specimen Type: Swab in Aptima Multitest Swab Transport Media; Dry swabs of skin lesion; Rectal and/or genital swabs with VTM/UTM, dry swab, or Aptima Multitest Swab Transport Media; CSF; Urine; Serum/Plasma; Whole blood; Breast Milk
Collection Instructions: Swab the lesion vigorously, to ensure adequate sample is collected. DO NOT UNROOF LESION.
Forms & Requisitions
UW Medicine Locations: Place order in Epic for test "Mpox Virus Qualitative PCR" (lab test code MPXQLT).
Outside Locations/Reference Laboratory Clients: Include a completed Virology requisition with the specimen and specify "Monkeypox Virus Qualitative PCR" in the "other requests/comments" area.
Handling Instructions
Storage and Transport (Reference Laboratory Clients):
- Swabs in UTM/VTM or Dry swab: Ship samples on dry ice. If -10°C or colder freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 7 days of collection. Samples stored at 2-8°C greater than 7 days old may be rejected. Do not freeze/thaw.
- Swab in APTIMA Tube: Store and transport at ambient temperature within 30 days of collection.
- Cerebrospinal fluid: 500µL CSF in a sterile container. Transport CSF on ice, store at 2 to 8°C for up to 7 days post collection. If there is a greater than 7 days delay before testing of the specimen, store specimen at -60 to -85°C. Do not freeze/thaw.
- Serum/Plasma: Separate plasma/serum from whole blood within 24 hours of collection. Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 7 days of collection. Samples stored at 2-8°C greater than 7 days old may be rejected. Do not freeze/thaw.
- Clear non-cellular fluid: Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 7days of collection. Samples stored at 2-8°C greater than 7 days old may be rejected. Do not freeze/thaw.
- Breast Milk: Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 7days of collection. Samples stored at 2-8°C greater than 7 days old may be rejected. Do not freeze/thaw.
