Faxing to American Clinical Reference Laboratory — FAQ

No. American Clinical Reference Laboratory routes faxes to separate office lines, so the medical records office and the client services and account office do not share a number. What you send to the medical records office will not reach the client services office. Confirm the correct line for the office you are reaching before you send. Which line is right depends on the office, not the lab as a whole.

Include the identifiers staff use to match a specimen: full name, date of birth, and record number. On the cover sheet, name the medical records office or the receiving office so it lands with the right team. Attach the signed authorization when the fax is a records or results request. Complete, legible identifiers are what move the order fastest.

American Clinical Reference Laboratory receives faxes at any hour, but the offices that process them keep set schedules. Records and client services offices work weekday business hours. The laboratory team handles add-on and stat orders on the day's testing schedule. Routine copies follow the office's normal queue rather than jumping ahead.
