Testing for Syphillis
- Prove Infection (3)
- Repeat Infection (1)
Prove
- TB haemoglutination assay
- TP particle agglutination assay
- Chemiluminescence assay
Repeat
= rapid plasma reagin test
Should be negative after treatment
RPR test = refinement of VDRL
What is the recommendation for hepatitis C exposure?
Monthly Hep C virus surveillance
HbsAg
What is it?
Antibody?
First marker of acute infection
If present less than 6 months = acute infection
Persists in chronic infection
Antibody
= anti-HBS
- Produced in response to infection OR in vaccination
= either resolved infection or vaccination
Hepatitis serology in vaccination
anti-HBS positive ONLY
