Thank you for your inquiry. From what we gather from the question, you were asking about HIV transmission by contact between an open wound and a surface with blood on it.
From the information given, this scenario is determined to be No risk (Transmission of HIV is not possible in the given scenario).
The scenario mentioned above does not meet the three components of the transmission equation. Assuming that the surface did have blood on it, in order for HIV to be transmitted it would need direct access to the bloodstream via large open wounds/cuts that were visibly bleeding. HIV needs a very controlled environment to survive and does not reproduce outside of the human host. HIV outside of the body depletes in concentration rapidly (90-99% within several hours), meaning that the risk of transmission is essentially zero (1).
Recommendation: No need for HIV test with the scenario provided, refer to a healthcare professional for other health related questions.
