The Department of Veterans Affairs does have a policy in place regarding test results:

Results are communicated to patients no later than 14 calendar days from the date on which the results are available to the ordering practitioner.  Significant abnormalities may require review and communication in shorter time frames and 14 days represents the outer acceptable limit.  For abnormalities that require immediate attention, the 14-day limit is irrelevant, as the communication should occur in the time frame that minimizes risk to the patient.
