Study Notes
Granulocytes and Blood Studies
- The rarest type of granulocyte is basophil.
- Abnormal MCHC values can arise from artifacts, often due to hemolysis or rouleaux formation.
- Blood collection tubes for PT (Prothrombin Time) and PTT (Partial Thromboplastin Time) assays should be citrated tubes to prevent coagulation.
Biopsy and Diagnosis
- Common sites for superficial biopsies include skin, mucous membranes, and subcutaneous tissue; however, deep organs are excluded.
- For diagnosing DIC (Disseminated Intravascular Coagulation), all laboratory abnormalities must include fibrinolysis factors, except for the presence of normal platelet counts.
Cytology and Enzyme Indicators
- In vaginal cytology during estrus, the predominant cell type is keratinized epithelial cells.
- The enzyme that indicates cholesterol disease is cholesterol esterase.
- The most common clinical sign associated with thrombocytopenia is the development of petechiae and ecchymosis.
Erythrocyte Maturation
- As erythrocytes mature, the cells progressively lose their nucleus and decrease in cell size.
- Alive spermatozoa will appear as motile and intact when stained with eosin/nigrosin.
Coagulation and Hemorrhaging
- TRUE: Coagulation abnormalities can lead to extensive hemorrhaging.
- Residual RNA aggregates in immature RBCs indicate possible reticulocytosis or RBC immaturity.
- Ingestion of certain pesticides, such as warfarin, could prolong a patient's PT and PTT.
- TRUE fact about anticoagulants: They are used to prevent thrombosis and facilitate lab tests.
- The refractive index is a measure used to assess the concentration of solutions, important in various hematological tests.
