5 EVALUATION CRITERIA The evaluation criteria used in the MLE Program is in accordance with the Clinical Laboratory Improvement Amendments of 1988 (CLIA 88) federal requirements for proficiency testing. The criteria are included below. Qualitative For qualitative procedures, evaluation is based on participant or referee consensus. If participant consensus is not reached, CMS requirements call for grading by referee consensus. A minimum percentage of participants or referee laboratories must receive a passing score or the challenge is not evaluated due to lack of consensus. These percentages are listed below. Crystal Identification Blood Cell Identification Urine Dipstick Urine hcg Microalbumin (Semi-Quantitative) Fecal Occult Blood Urine Sediment Identification Provider-Performed Microscopy KOH Skin Preparation ABO Group Rh Factor (D Type) Unexpected Antibody Detection Antibody Identification Compatibility Testing 80% Consensus 80% Consensus 80% Consensus 80% Consensus 80% Consensus 80% Consensus 80% Consensus 80% Consensus 80% Consensus 95% Consensus 95% Consensus 95% Consensus 95% Consensus 95% Consensus Quantitative For quantitative procedures, a mean and standard deviation (SD) are calculated for each peer group consisting of 10 or more laboratories except for QBC Hematology and Coagulation (CG Specimens) which consist of peer groups of 5 or more laboratories. Acceptable performance is established on a target value the intervals below. An explanation on how to calculate the range of acceptability based upon these limits is also provided in your MLE Program Guide on page 37 under the heading Acceptable Ranges for Quantitative Results.

51 2014 M1 Specimens BC-1 through BC-6 Case History: A 26-year-old male presented for his first physical. He reported that he recently began an exercise program to overcome his life-long feelings of weakness and chronic fatigue. However, he was unable to make any progress toward his goal of physical fitness due to having dizzy spells whenever he tried to exert himself. Upon examination, the patient appeared pale, his pulse was elevated, and the physician heard a slight heart murmur. A CBC was performed, and the results appear below. Test Results Reference Range WBC 8.5 x 10 9 /L x 10 9 /L RBC 4.84 x /L x /L HGB 10.4 g/dl g/dl HCT 35.0 % % PLT 360 x 10 9 /L x 10 9 /L MCV 72 fl fl MCH 21 pg pg MCHC 30 g/dl g/dl RDW 16 % % This patient was diagnosed with hereditary sideroblastic anemia. Sideroblastic anemias are a group of hereditary and acquired disorders of heme synthesis. Heme is the red, ironcontaining portion of the hemoglobin molecule that carries oxygen. In the hereditary form, a genetic mutation disrupts the insertion of iron into developing heme molecules, which prevents red blood cells from making enough hemoglobin. This leads to a buildup of iron that would normally have been incorporated into hemoglobin. The body attempts to compensate for the low hemoglobin by absorbing even more iron from the diet. Serum iron and transferrin levels increase. Over time, severe complications such as heart disease and liver damage can evolve from the buildup of excess iron deposits in these organs. Signs and symptoms of hereditary sideroblastic anemia tend to appear in young adulthood, and result from a combination of low hemoglobin and iron overload. They include fatigue, dizziness, rapid heartbeat, pale skin, and enlarged liver and spleen. Disorders of iron metabolism often cause microcytic, hypochromic anemias. The peripheral smear of a patient with sideroblastic anemia may include distorted red blood cells, schistocytes, target cells, spherocytes, and basophilic stippling. A diagnostic feature of this disease is the presence of ringed sideroblasts (red cells containing iron deposits) on bone marrow smears stained with Prussian Blue MLE-M1 Participant Summary/ 51

52 BLOOD CELL IDENTIFICATION Specimen BC-1 Identification Labs Percent Performance Basophilic stippling % Acceptable The arrows in this photograph point to erythrocytes with basophilic stippling. These immature red blood cells have expelled their nuclei but still contain some residual RNA. The RNA is aggregated into small granular clumps that stain dark blue-purple. The clumps are evenly distributed throughout the cell, and may appear fine (smaller) or coarse (larger). Basophilic stippling is associated with increased RBC production, defective heme synthesis, anemia, thalassemia, and lead poisoning. These cells would be called reticulocytes only when examined with a supravital stain such as New Methylene Blue. To view another photo of basophilic stippling, see 2012 M3 Specimen BC-17. Specimen BC-2 Identification Labs Percent Performance Lymphocyte, reactive % Acceptable Immature/abnormal cell refer % Acceptable Monocyte % Lymphocyte % The arrow in this photograph points to a reactive lymphocyte. Reactive lymphs appear in a wide variety of forms, sizes and shapes. These large atypical lymphocytes are reacting to immune stimuli in the body. They are often increased in viral infections such as infectious mononucleosis. The cytoplasm is light blue, with peripheral basophilia- a deeper blue color at the extreme border. The edges of the cytoplasm tend to flow around the adjacent red blood cells. The nucleus is large, appearing slightly elongated or stretched. Some participants incorrectly identified this cell as a monocyte. Monocytes often appear to push away adjacent red cells with their cytoplasm, and lack the dark blue periphery that is typical of lymphocytes. To view another photo of a reactive lymphocyte, see 2013 M3 Specimen BC-14. To view a monocyte, see 2013 M1 Specimen BC / 2014 MLE-M1 Participant Summary

53 BLOOD CELL IDENTIFICATION Specimen BC-3 Identification Labs Percent Performance Hypochromic red cell % Acceptable Macrocyte % The arrows in this photograph point to hypochromic erythrocytes. A red blood cell is considered hypochromic when the zone of central pallor covers more than one-third of the diameter of the cell (or >3μm.) In normochromic (normal-colored) RBCs, the zone of central pallor comprises one-third or less of the total diameter of the cell. Hypochromic cells have more central pallor than a normal RBC due to lower concentration of hemoglobin. A decreased MCHC value is often associated with marked hypochromia. Specimen BC-4 Identification Labs Percent Performance Neutrophil-Segmented or band % Acceptable Hypersegmented neutrophil % The arrow in this photograph points to a segmented neutrophil. The cytoplasm of these normal cells is pale pink and filled with fine, violet-pink granules. The nucleus of the cell is divided into two to five segments, or lobes, connected by a thin thread-like filament. This filament connecting the segments must be visible to classify the cell as segmented. To view another photo of a normal seg, see 2013 M1 Specimen BC MLE-M1 Participant Summary/ 53

54 BLOOD CELL IDENTIFICATION Specimen BC-5 Identification Labs Percent Performance Microcyte % Acceptable Erythrocyte, normal % The arrows in this photograph point to microcytes. These small red blood cells have the same color, morphology, and central pallor as the normal RBCs in the field, but are simply smaller in size. The nucleus of a mature, resting lymphocyte such as the one in this photo is a good reference for estimating the size of red blood cells. A normal RBC will be approximately the same size as the lymph s nucleus. To view another photo of microcytes, see 2011 M3 BC-17. To view normal erythrocytes, see 2013 M1 specimen BC-2. Specimen BC-6 Identification Labs Percent Performance Pappenheimer body % Not graded Educational Challenge Howell-Jolly body % Immature/abnormal cell refer % Heinz body % The arrows in this ungraded educational challenge point to erythrocytes containing Pappenheimer bodies. Any condition that disturbs hemoglobin synthesis can cause Pappenheimer bodies. These red cell inclusions are small, blue, angular, irregular in size and shape, and tend to aggregate in small clusters near the edge of the cell. The cells would be called siderocytes when viewed with Prussian Blue staining, which would confirm that these particles contain iron. Howell-Jolly bodies are spherical and larger than Pappenheimer bodies. Heinz bodies are not visible in Wright-stained smears. To view another photo of Pappenheimer bodies, see 2009 M2 Specimen BC-11.

79 Specimen US-1 Identification Labs Percent Performance Amorph urate/phosphate crystal % Acceptable Granular cast % Identification Unknown Refer % Yeast/fungi % Bacteria % White blood cell(wbc) % Fiber/fecal contamination % RBC/blood/hgb cast % The arrows in this photo point to amorphous urate crystals. Amorphous means without shape or form. Amorphous urate crystals are normal, nonpathologic crystals commonly seen in acidic, concentrated specimens that have been refrigerated. The specimen cup often contains a fluffy red precipitate described as brick dust. Microscopically, these small, formless urate crystals are identical to amorphous phosphate crystals, which are found in alkaline urines and form a white or colorless precipitate. To view another photo of amorphous crystals, see 2009 M1 Specimen US-2. Technical tip: Amorphous crystals can be so numerous that they obstruct the view of any other elements in the sediment. The crystals can be dissolved by washing the sediment with warm saline or heating a tube of the urine or sediment in a hot water bath. Specimen US-2 Identification Labs Percent Performance Hyaline cast % Acceptable Waxy cast % Granular cast % Fiber/fecal contamination % The arrow in this photo points to a hyaline cast. Hyaline casts are the most commonly seen casts in the urine. They are colorless and smooth, with a finely wrinkled surface and no granules. The sides are parallel and the ends are blunt and rounded. Hyaline casts are normal, and frequently seen in the urine sediment of healthy people in small numbers (less than two per low-power field.) They may be increased after strenuous exercise or in other conditions, including renal disease. Waxy casts are more broad and square, with cracks and blunt ends. Granular casts have much more prominent granularity. To view a photo of a waxy cast, see 2006 M1 Specimen US-1. To view a granular cast, see 2008 M2 Specimen US-3. Technical tip: Hyaline casts have a low refractive index, which makes them hard to see if the microscope s illumination is not set correctly. Use subdued lighting to examine urine sediment, with the sub-stage condenser raised all the way up, and the condenser iris diaphragm approximately 70% closed / 30% open. Do not lower the condenser to decrease brightness. This reduces the resolution and sharpness of the image, which could cause you to miss important elements like casts.

80 PROVIDER-PERFORMED MICROSCOPY (PPM) Wet Mount Preparation Specimen PPM-1 Identification Labs Percent Performance White blood cell (WBC) % Acceptable Red blood cell (RBC) % Starch (Talc) granules % Yeast/fungi % The arrows in this photograph of a vaginal wet mount point to white blood cells. The nuclei within the cells give them a granular appearance. Presence of a large number of white blood cells is associated with infection such as Candidia, herpes, trichomonas, gonorrhea, or chlamydia. Red blood cells are smaller in size and appear hollow, sometimes resembling donuts or inner tubes. To view a photo of red blood cells in a wet mount, see 2011 M1 Specimen PPM-1. KOH Preparation Specimen PPM-2 Identification Labs Percent Performance Yeast/fungal elements absent % Acceptable Yeast/fungal elements present % Yeast and fungal elements are absent in this photograph of a KOH vaginal wet mount. The numerous small objects in this photograph are bacteria. To view a photo of yeast in a KOH prep, see 2013 M1 Specimen PPM / 2014 MLE-M1 Participant Summary

81 PROVIDER-PERFORMED MICROSCOPY (PPM) Sperm Identification Specimen PPM-3 Identification Labs Percent Performance Sperm present % Acceptable Sperm absent % Three sperm are present in this photograph of a vaginal wet mount preparation. Nasal Smear Specimen PPM-4 Identification Labs Percent Performance Eosinophils absent % Acceptable Eosinophils present % Eosinophils are absent in this photograph of Wright-stained nasal mucus. The purpose of examining the leukocytes in stained nasal secretions is to differentiate allergic conditions from infections. Eosinophils are a specific type of leukocyte (white blood cell) that is increased in allergic conditions. The cells shown in this photo are not eosinophils. They indicate infection rather than allergy. Eos have a unique red-orange color that makes them easy to spot and identify. The cytoplasm of an eosinophil is filled with large, round, orange-staining granules that surround the purple nucleus but do not obscure it from view. The orange color comes from the dye eosin, which is a component of Wright stain. To view a photo of eosinophils, see 2013 M2 Specimen PPM-10. Specimen PPM-4 is graded by 100% referee consensus MLE-M1 Participant Summary/ 81
