(1) serologic tests on unknown specimens must be run concurrently with a positive control serum of known titer or controls of graded reactivity plus a negative control in order to detect variations in reactivity levels;

(2) controls for all test components including, but not limited to, antigens, complement, and erythrocyte indicator systems, must be used to ensure reactivity and uniform dosage;

(3) test results must be reported only after the predetermined reactivity pattern of the controls is obtained;

(g) Clinical chemistry services must be in compliance with the following requirements:

(1) each instrument or device must be recalibrated or rechecked at least once each day that it is used;

(2) records which document the routine precision of each method, automated or manual, and its recalibrated schedule must be maintained and made available to laboratory personnel and the department;

(3) at least one standard and one reference or control sample must be included with each test run on unknown specimens;

(4) control limits for standards and reference samples must be recorded along with a record of the action taken when test results are outside acceptable limits; and

(5) screening or qualitative chemical urinalysis must be checked daily by use of suitable reference samples.

(h) Immunohematology services must be in compliance with the following requirements:

(1) ABO grouping must be performed by testing unknown red cells with anti-A and anti-B grouping serums licensed under 21 C.F.R. Part 610 as in effect April 30, 1983, or possessing equivalent potency, using the technique for which the serum is specifically designed to be effective;

(2) for confirmation of ABO grouping, the unknown serum must be tested with known A1 and B red cells;

(3) the Rh o (D) type must be determined by testing unknown red cells with anti-Rh o (anti-D) typing serum licensed under 21 C.F.R. Part 610 or possessing equivalent potency, using the technique for which the serum used is specifically designed to be effective;

(4) anti CD, DE, and CDE sera used for donor typing must be federally licensed or of equivalent potency;

(5) all Rh o (D) negative blood specimens (except recipients) must be tested for the Rh o (D) variant (Du);

(6) a control system of patient cells suspended appropriately with an anti-D reagent in use must be used when the test is performed in a protein medium; and

(7) the reliability of reagents (antisera, known test cells and antiglobulin-Coombs serum) which are used for ABO grouping, Rh typing, antibody detection, and compatibility determinations must be tested for reactivity on each day of use and when a new lot of reagents is first used, unless the laboratory keeps records which demonstrate that accuracy is high and such frequency of testing is unnecessary.

(i) Hematology services must be in compliance with the following requirements:

(1) instruments and other devices that are used in hematological examination of specimens must be recalibrated, retested, or reinspected, as appropriate, each day they are used;

(2) each procedure for which standards and controls are available must be rechecked each day of use with standards or controls covering the entire range of expected values;

(3) the one-stage prothrombin time test and other related tests must be run in duplicate, unless the laboratory can demonstrate that low frequency of random error or high precision make such testing unnecessary;

(4) reference materials including hemoglobin pools and stabilized cells must be tested at least once each day they are used to insure accuracy of results; and

(5) the accuracy and precision of instruments or devices used for blood cell counts, hematocrit and hemoglobin measurements must be tested each day they are used.

(j) Exfoliative cytology must meet the following requirements:

(1) the laboratory director or an individual in a supervisory position who is either qualified as a cytotechnologist or who is otherwise qualified in the field of cytology must rescreen for proper staining and correct interpretation a random sample of at least 10 percent of the gynecological smears which have been interpreted by other laboratory personnel to be in one of the benign categories;

(2) all gynecological smears interpreted by screeners to be in the "suspicious" or positive categories must be confirmed by the laboratory director or by an individual in a supervisory position who is either qualified as a cytotechnologist or who is otherwise qualified in the field of cytology;

(3) the test report of all gynecological smear tests interpreted in (2) of this subsection must be signed by a physician qualified in pathology or cytology;
