New Testing Algorithms for HIV and the Impact on Public Health

For nearly 25 years, the standard algorithm used in the U.S. for serological diagnosis of HIV infection has been a two-step process involving a screening immunoassay followed by a confirmatory Western blot. Significant advances in HIV diagnostics over the years have led to the development of a new alternative algorithm proposed by the Centers for Disease Control and Prevention (CDC) and the Association of Public Health Laboratories (APHL). Implementation of this new HIV testing algorithm should decrease reporting times for results and improve linkage to care, differentiation infections with HIV-1 from HIV-2, and enhance our ability to identify acute primary HIV infections.

 

Learning Objectives:

  1. List the different types of tests that can be used for detecting HIV infection.
  2. Understand the sequence of tests used in the recommended HIV laboratory testing algorithm.
  3. Describe the clinical and public health advantages of early diagnoses of HIV infection.

Multiplex Testing for Enteric Pathogens- Is It Worth It?

Globally, acute infectious gastroenteritis is a substantial public health burden resulting in 3-5 billion cases of diarrhea and 4-10 million deaths each year. The microbial pathogens responsible for these infections are diverse and difficult to distinguish clinically or by current laboratory methods. Recent developments in technology have led to the introduction of multiplex assays that can simultaneously detect and identify multiple gastrointestinal pathogens, including bacteria, viruses and parasites. The clinical utility, impact on outcomes, and cost-effectiveness of this approach remains to be determined.

Learning Objectives:

  1. To review viral, bacterial and parasitic causes of diarrhea.
  2. To provide an overview of commercial multiplex enteric pathogen diagnostic tests.
  3. To contrast near-patient and batch-testing approaches.
