Summary Introduction
To review:
The relationship between following observations: 5% of red blood cells were reticulocytes, the presence of polycythemia and a hematocrit of 65%.
Introduction:
Erythrocytes are also known as red blood cells (RBCs) and they serve as transporters of the respiratory gases in the human body. Erythrocytes are the most abundant cells in the human body. Red blood cells are the only class of blood cells that are not circular in shape and possess a biconcave disc shape.

Xin’s blood was drawn and testing was conducted. His hematocrit was 45% and white-blood cell count was 2,500 white-blood cells/mm3, with the differential showing neutrophils 65%, lymphocytes 25%, monocytes 10%. A biopsy was taken of one of the discolored lesions and cell culture. After three days of growth the cells were confirmed as coming from malignant cancerous tissue. A magnetic resonance image (MRI) of the area around the skin lesions on Xin’s inner thigh revealed enlarged lymph nodes, a sign of potential metastasis. DNA sequencing of the lesion biopsy revealed DNA consistent with human herpesvirus 8, known as Kaposi’s sarcoma-associated herpesvirus, leading to the diagnosis of Kaposi’s sarcoma.
- What Disorders can be ruled in and out from this diagnosis?
In hereditary hemolytic anemia, massive destruction of red blood cellsoccurs. Would you expect the reticulocyte count to be above or belownormal? Explain why one of the symptoms of the disease is jaundice. In 1910, physicians discovered that hereditary hemolytic anemiacan be treated successfully by removing the spleen. Explain why thistreatment is effective.

- A white cell differential was performed for an adult female, with the following percentages of cells counted:Neutrophils = 25%, Lymphocytes = 69%, Monocytes = 5%, Eosinophils = 1%, Basophils = <1%Given that the total white cell count for this individual is 8.1x109/L, calculate the absolute number of lymphocytes per litre of blood. Discuss possible causes for any of the white cell differential counts which do not fall within the expected reference ranges.arrow_forwarda 58-year-old Asian male .He visited his physician because he noticed dark colored lesions on his inner thighs, have increased in number, size. For the last three months he has been feeling weaker and more fatigued than usual; his weight dropped from 170 to 155 pounds. Xin’s blood was drawn and testing was conducted. His hematocrit was 45% and white-blood cell count was 2,500 white-blood cells/mm3, with the differential showing neutrophils 65%, lymphocytes 25%, monocytes 10%. A biopsy was taken of one of the discolored lesions and grown in cell culture. After three days of growth the cells were confirmed as coming from malignant cancerous tissue. A magnetic resonance image (MRI) of the area around the skin lesions on Xin’s inner thigh revealed enlarged lymph nodes, a sign of potential metastasis. What possible Diagnosis or disorders can you rule out for this paitentarrow_forwardA 51-year-old white man was admitted to the burn unit of a local hospital following an accident at a local foundry. Several STAT laboratory blood tests were ordered, including a complete blood count. Laboratory Data: The hemoglobin, hematocrit, and red blood cell (RBC) count were all slightly elevated. The total leukocyte count was 15.8 × 109 /L. The differential count was as follows: Band neutrophils 12% Segmented neutrophils 65% Lymphocytes 23% Light blue-gray inclusions were observed in the cytoplasm of many of the bands and segmented neutrophils. What is the etiology of the abnormal quantitative findings in this patient’s complete blood count? What are the blue-gray vacuoles in the cytoplasm of the leukocytes?

- A male college freshman is seen at the college health service complaining of general fatigue, a sore throat, and swollen lymph nodes in his neck. A throat culture is done, and blood is drawn for hematology studies and a rapid MonoSlide test. Hematology results show a normal hemoglobin value and a slight increase in the white cell count, with many large, reactive lymphocytes seen in the differential. A rapid strep test is negative, but a second swab is cultured on sheep blood and incubated, with the result to be read in 18 hours. Result from the MonoSlide test is positive.
