Which lab test results are prohibited from being disclosed via electronic means?

The correct choice addresses the sensitive nature of certain lab test results related to HIV, Hepatitis, and drug abuse. These test results pertain to confidential medical information that is considered particularly private and sensitive, often governed by stringent privacy regulations.

Federal laws such as the Health Insurance Portability and Accountability Act (HIPAA) and specific state laws impose strict guidelines on how personal health information should be handled, particularly for conditions that carry a stigma or may be associated with discrimination. Disclosing such sensitive information via electronic means increases the risk of unauthorized access and breaches of confidentiality, which is why it is prohibited for these types of test results.

In contrast, cholesterol levels, blood pressure readings, and general health screenings do not fall under the same level of confidentiality and can typically be shared via electronic means, given that the appropriate privacy safeguards are in place. These other options relate to general health status that does not have the same implications associated with revealing private medical conditions. Thus, the prohibition on disclosing results specific to HIV, Hepatitis, and drug abuse is rooted in a commitment to protect patient privacy and uphold ethical standards in the handling of sensitive health information.
