In order for Hepatitis B screening on Patient Dashboard to operate correctly, all of the following must be in place.
- The antigen and antibody lab test results must be mapped to a screening term. Typically, these are mapped to the HEPAG and HEPAB screening terms, and these can be downloaded by clicking here.
- The following concepts must be mapped correctly to these screening terms:
Both antigen and anitbody results must be recorded in screening.
- HEPBAG to the screening term containing the antigen result.
- HEPBAB to the screening term containing the antibody result.
The antigen result must be either "NEGATIVE" or "POSITIVE" (case insensitive).
If the antigen result is negative, then an antibody result > 10 indicates that the patient is immune and thus they will get a green traffic light.
If the antigen result is negative, then an antiobdy result <= 10 indicates that the patient is not immune and thus should be vaccinated. The traffic light will then only be green if the patient has been given the full suite of Hepatitis B vaccinations.
If the antigen result is positive, then the antibody result is ignored as the patient is a carrier (and thus will get a yellow traffic light).
If there are no screening results (perhaps the patient has been screened elsewhere but the Hep B status of the patient is known, this can be recorded directly within the outcome of a screening term, and this screening term mapped to the HEPBOUTCOME concept. This screening term is created by the Hepatitis B Advanced Form which can be separately downloaded.
The outcome of this screening term must be one of the following:
