ALL RESULTS REPORTED IN UG/ML. PATIENT 1, SAMPLE 1. THE ORIGINAL PHNO RESULT WAS 140.10. THE ORIGINAL PHNY RESULT WAS 142.73. BOTH RESULTS WERE ACCOMPANIED BY DATA FLAGS AND WERE REPORTED OUTSIDE THE LABORATORY. THE SAMPLE WAS REPEATED WITH DILUTION WHICH YIELDED A PHNO RESULT OF 233.5 AND A PHNY RESULT OF 179.04. THESE RESULTS WERE ACCOMPANIED BY DATA FLAGS. ON (B)(6) 2010, THE USER REPEATED THE SAMPLE A THIRD TIME WITHOUT DILUTION WHICH YIELDED A PHNO RESULT OF 17.11 AND A PHNY RESULT OF 22.14. PATIENT 1, SAMPLE 2. THE ORIGINAL PHNO RESULT WAS 142.34. THE ORIGINAL PHNY RESULT WAS 130.24. BOTH RESULTS WERE ACCOMPANIED BY DATA FLAGS AND WERE REPORTED OUTSIDE THE LABORATORY.
