  or institution is evaluated and recognized as
  meeting certain predetermined standards. Usually
  non-government and voluntary. Examples ASCP or

Unit 1 Introduction to Laboratory Medicine

• Confidentiality
• As a member of the health care team, it is
  expected that we will always respect the privacy
  of our patients.
• This includes not talking about our patients,
  their diagnosis or prognosis, or their test
  results to anybody except those that have a
  right to know, such as other health care
  professionals working with this patient or the
  parents of a minor child.

37
Unit 1 Introduction to Laboratory Medicine

• Confidentiality also means that you protect the
  patients right to privacy in such areas as
• Keeping the patient covered to the extent
  possible when the patient cannot do this herself.
• Not calling out to patients in doctors office
  about the nature of their visit to the doctor or
  their treatment when other patients are in
  earshot.

38
Unit 1 Introduction to Laboratory Medicine

• The Health Insurance Portability and
  Accountability Act of 1996 (HIPAA, Title II) was
  passed by Congress to address patient privacy in
  the sharing of electronic databases, but was
  expanded to include patient privacy in ALL
  aspects of patient care and interaction.
