The smear offers a window into the functional status of the bone marrow the factory producing all blood elements.
Atypical lymphocytes in blood smear. Tzanck smear test is 97 sensitivity and 86 specificity for the diagnosis of basal cell carcinoma. Atypical lymphocytes - see Reactive lymphocytes below. It has a wide range of uses including distinguishing viral infections from bacterial infections evaluating anemia looking for causes of jaundice and even diagnosing malaria.
In some cases the peripheral smear alone is sufficient to establish a diagnosis. Lymphocytes B cells and T cells Monocytes. Peripheral blood smear showed many atypical lymphocytes with petal-shaped nuclei like flowers as seen in the photograph.
About this page. Are white blood cell abnormalities associated with disease. A blood smear also referred to as a peripheral smear for morphology is an important test for evaluating blood-related problems such as those in red blood cells white blood cells or platelets.
It is particularly important when assessing cytopenic states eg anemia leukopenia thrombocytopenia. Five types of white blood cells also called leukocytes normally appear in the blood. Acantholytic cell and multinucleated.
Lymphocytes normal atypical few mature band. Auer rods are seen in myeloblasts and are pathognomonic of acute myeloid leukaemia. Her total leukocyte count was 306 x 109L.
Review of the smear is an important adjunct to other clinical data. Isolated or clusters of Pagets cells Kaposis sarcoma. Blast cells are abnormal immature nucleated precursor WBCs pushed out from the marrow into the circulation by processes such as myelofibrosis or leukaemic infiltration.
Acid-fast bacilli are detectable in the urine by microscopy and culture. Tuberculosis of the kidney and urinary tract. The test shows if the.
Microscopy is relatively insensitive as in many. John B Eastwood Catherine M Corbishley in Tuberculosis 2009. Atypical lymphocytes Pagets disease.
Peripheral blood immunophenotype noted negative markers for myeloid and B lymphoid lineage CD10 CD19 CD3 CD5 CD7 cyto-CD3 TCR CD16 CD56 and strongly positive for CD4 and CD25 and also CD2 which was atypical. Immature WBC andor WBC with abnormal alterations may also be seen. Csw lsuhsc 2001 menu An abnormal number andor distribution of leuko- cytes WBC may be seen in disease.
The smear is stained with a special dye which helps tell the difference between various types of white blood cells. Cytologic atypia of keratinocytes Melanoma. The immature and abnormal cells are distinguishable from normal cells by their morphologic characteristics.
