Q: At which of her healthcare interactions could HIV testing have been performed?
1. When she first registered with her GP?
2. When she presented to the ED with weight loss and was admitted?
3. When she presented to Respirology OPD with suspected PUO, previous Hep B was identified and latent TB was diagnosed?
4. Should she have been referred to GUM to see a trained counsellor before HIV testing?

3 missed opportunities! If current guidelines used, HIV could have been diagnosed up to 8 years earlier
Learning Points• This patient came from a country of low HIV prevalence
and was probably not believed to be at risk of HIV infection
• Because of this the otherwise excellent medical teams looking after her presumably did not think of HIV even though the diagnosis seems obvious with hindsight
• However, the suspected PUO and Hepatitis B and TB diagnoses were a red flag for possible HIV infection
• A perceived lack of risk should not deter you from offering a test when clinically indicated
• Antiretroviral therapy (ART) has transformed treatment of HIV infection
• The benefits of early diagnosis of HIV are well recognised - not offering HIV testing represents a missed opportunity
• UK guidelines recommend screening for HIV in adult populations where undiagnosed prevalence is >1/1000 as it has been shown to be cost-effective
• HIV screening should be a routine test on presentation of PUO or weight loss of otherwise unknown cause
• HIV screening should be routine in services for patients diagnosed with Hepatitis B and TB
