Calibration methods for automated hematology instruments.
Recent CAP survey data have documented marked improvement in the reproducibility of hematologic tests. The favorable outcome is attributable largely to the widespread use of automated whole-blood analyzers. Calibration variability, however, detracts from this enhanced precision, and there are clear indications that improvement is necessary. Primary calibration methods for hemoglobin, hematocrit and cell counting procedures are presented. The methods of applying these primary calibration methods to automated whole-blood analyzers are delineated. The use of both preserved reference blood and statistical control technics for the identification of calibration loss is described.

The prediction of prothrombin time system performance using secondary standards.
A method for the comparison of prothrombin time systems using single large lots of lyophilized plasma in the College of American Pathologists Surveys is presented. Systematic biases for prothrombin time methods as well as for thromboplastins have been measured, and their use allows a very accurate (within 2.25%) prediction of the prothrombin time for the great number of prothrombin time systems presently being used in the United States.

The reticulocyte. An approach to definition.
Experiences of the CAP Survey Program in reticulocyte counts and morphologic identification of reticulocytes from 1971 to 1974 are reviewed. Problems of morphologic identification are reflected in an excessive variance of reticulocyte counts. Statistical sources of variations in counting are identified. The older, original descriptions and definitions of morphologic criteria are reviewed and discussed in relationship to Survey performance.

Studies of fibrinogen measurement in the CAP survey program.
A review of the College of American Pathologists' Surveys experience in fibrinogen testing from 1967 to 1974 is reported. Trends in fibrinogen methodology and the emergence of a consensus choice of the modified thrombin time method are documented. The reasons for these changes from former methods are discussed.
