This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Human Immunodeficiency Virus — HIV Screening and Testing Guide. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Offer HIV testing through informed consent and a non-stigmatizing risk and prevention discussion.
  • Use a fourth-generation laboratory test or the approved local rapid-testing algorithm and recognize the window period.
  • Arrange urgent confirmatory testing and linkage to HIV care for a reactive result, while addressing partner and public-health requirements.
  • Offer HIV testing with consent whenever the result will inform care, without requiring disclosure of a particular risk identity.

Practical assessment and management workflow

1
Explain the test and confidentiality and identify timing of the last possible exposure.
2
Use a laboratory antigen-antibody or appropriate point-of-care pathway and understand its window period.
3
Arrange supplemental testing and rapid linkage after a reactive result.
4
Repeat testing after a recent exposure when the initial result may fall within the window period.

Safety, red flags and urgent escalation

  • Do not delay post-exposure prophylaxis while waiting for a test result.
  • Symptoms compatible with acute HIV after a recent exposure require antigen-antibody and nucleic-acid assessment.
  • Communicate results through a reliable confidential process and follow provincial reporting rules.
