| The blood study from which this smear was obtained revealed an MCV of 115 femtoliters (fl).Normal MCV values in adults= 80 - 90 fl.Normal MCV values in full-term infants= 98 -108 fl.Which of the following conditions may be indicated by the results seen on this peripheral blood smear? | View Page |
| Criteria for peripheral blood smear review Initial analysis of the peripheral blood picture is made in most clinical laboratories with an automated instrument. Samples are selected for further analysis when quantitative or qualitative abnormalities beyond a defined standard are found. The following are examples of quantitative RBC abnormalities that may prompt a blood smear review. Each laboratory, however, should develop its own guidelines: Hgb: < 8 or >18 g/dL (<10 or > 21g/dL in a newborn)Hct: <20% or > 60% in adults (<40% or >65% in a newborn)MCHC: <29 g/dLMCV: <69 femtoliters (fl) or >110flFlags generated by the hematology analyzer that indicate possible red cell abnormalities or spurious resultsAny of these findings should be followed up with a peripheral blood smear review. | View Page |
| Normal Red Cells Normal red cells are seen in this field. Mature erythrocytes can be described as round, elastic, non-nucleated, bi-concave discs which appear buff colored on Wright's stained smears. Notice that many of the cells have an area of central pallor which covers about one-third of the cell. The pallor occurs as a result of the disc-shaped cells being spread on the slide. Normal mature red blood cells have an average diameter of 7.2 microns with a range of 6-9 microns. This is approximately the same size as the nucleus of a small lymphocyte, which is often used as a guideline when determining the size of the red cells on a slide.
The average thickness of a normal mature red blood cell is 2.1 microns with a mean corpuscular volume (MCV) of 87 cubic mircons/femtoliters. | View Page |
