How to Fax Lab Results — Secure, HIPAA-Compliant Transmission
Lab results sit among the most sensitive documents in a patient's chart, carrying diagnostic values that drive treatment decisions. Sending them to ordering physicians, specialists, and care team members by fax remains the fastest and most widely compatible route in clinical practice. Because results are PHI, with extra protection for HIV testing, genetic testing, and substance abuse records under 42 CFR Part 2, the Professional plan at $39.99 a month and up provides the signed BAA and encryption a lab needs to transmit them within HIPAA.
How to Fax a Lab Results
- 1Generate or scan the lab result report as a PDF, ensuring all values, reference ranges, and critical flags are clearly legible
- 2Verify the ordering physician's current fax number against your directory or call to confirm
- 3Log in to Send FAX Mail and create a new fax
- 4Upload the lab result PDF and enter the recipient's fax number
- 5Add a HIPAA confidentiality cover sheet identifying the sender, recipient, and that the document contains protected health information
- 6Send and retain the delivery confirmation in the patient record as evidence of timely result transmission
Document Format
Lab reports should include the patient's full name, date of birth, specimen collection date, and ordering provider on every page. Reference ranges must appear alongside each result value for clinical interpretation. Critical values should be highlighted or flagged conspicuously. Use high-contrast black text — colored highlighting may not transmit visually via fax.
Legal Considerations
Lab results are PHI under HIPAA with additional protections for HIV test results, genetic testing, and substance abuse treatment records under state laws and 42 CFR Part 2. Timely notification of critical lab values may be legally or professionally required. Some states mandate direct patient notification of certain results within specified timeframes.

Recent updates
Federal interoperability rules keep pushing healthcare past the fax machine
CMS has advanced a series of interoperability rules that press hospitals, payers, and providers toward electronic data exchange and standardized claims attachments. The direction of travel is clear: paper and analog fax workflows are being replaced by digital transmission that carries an auditable record — which is exactly what a cloud fax with delivery confirmation provides for offices not yet on a full EHR pipeline.
CMS →Healthcare breach reporting keeps document handling under scrutiny
Ongoing reporting on HIPAA breaches and OCR settlements underscores how much scrutiny falls on how medical documents are stored, sent, and received. Sending records through a controlled, access-logged channel rather than an unmanaged machine reduces the mishandling risks that show up repeatedly in breach analyses.
HIPAA Journal →HHS OCR continues enforcing HIPAA safeguards on how PHI is transmitted
The HHS Office for Civil Rights enforces the HIPAA Security Rule's requirement that covered entities apply administrative, physical, and technical safeguards to protected health information in transit. Faxing PHI is permitted, but the sending practice is responsible for confirming the destination and controlling access — the reason healthcare senders favor a channel that logs each transmission and its recipient.

Faxing a Lab Results — FAQ
HIPAA lets patients ask for their results to be sent directly to them. The lab still has to verify the patient's fax number with care first, because results delivered to a wrong number are a reportable breach.
They are. CAP and JCAHO standards generally require immediate verbal notification of a critical value, with the faxed report serving as the documented written follow-up after that call is made. Use Send FAX Mail for that written record once the verbal contact is complete.
The Professional plan at $39.99 a month covers 2,000 pages with the HIPAA BAA, enough for a reference lab sending results to dozens of physicians a day, and the Business plan at $79.99 a month raises the allowance to 5,000 pages along with capacity for multiple staff. A lab that reaches its allowance steps up to the next plan rather than paying per page.
Number selection is free. Dedicated fax modules inside a lab information system often run into the hundreds of dollars a month, whereas Send FAX Mail connects through email-to-fax with most LIS platforms for $12.99 to $79.99 a month depending on volume.
