LOINC Code 69939-7: T. rubrum DNA NAA+probe Ql (Nail)

69939-7 is a LOINC code used to identify T. rubrum DNA NAA+probe Ql (Nail) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Trichophyton rubrum DNA. It is commonly used with the system or sample type Nail.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Trichophyton rubrum DNA. It is commonly used with the system or sample type Nail.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: Probe.amp.tar

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Trichophyton rubrum DNA [Presence] in Nail by NAA with probe detection
  • Trichophyton rubrum DNA
  • This term was created for, but not limited to, Staten's Serum Institute Dermatophyte-Trichophyton rubrum test kit, which is is an in vitro diagnostic detection of dermatophytes in general (pan-dermatophytes) (see LOINC 70027-8) as well as Trichophyton rubrum. The primer pairs are directed towards genes encoding chitin synthase 1 (chs1, 366bp amplicaon size) for detection of dermatophytes and ITS2 (internal transcribed spacer, 203bp amplicon size) for detection of T. rubrum.
