Study Notes
Blood Cells and Coagulation
- The rarest type of granulocyte is the basophil.
- Abnormal MCHC values can be caused by artifacts due to hemolysis, lipemia, or hyperbilirubinemia.
- For PT and PTT assays, sodium citrate tubes should be used for blood collection.
- The buccal mucosa is not typically biopsied for superficial locations.
Coagulation and Hemostasis
- To diagnose DIC, thrombocytopenia must not be present.
- Vitamin K antagonists play a role in inhibiting blood coagulation in the body.
- A refractive index measures the degree of bending of light as it passes through a medium.
Cytology and Cellular Development
- During Estrus, superficial cells are predominant in vaginal cytology.
- As erythrocytes mature, they lose their nucleus and organelles.
- Mature RBCs of mammals are biconcave discs.
Sperm Analysis
- Alive spermatozoa appear pinkish-red when using the eosin/nigrosin stain.
Lymphocytes and Cholesterol
- Physiological causes or diseases can cause variations in lymphocyte numbers.
- Lymphocytes are the smallest white blood cells.
- The enzyme that indicates cholesterol disease is cholesterol esterase.
Urine Analysis
- Urine samples should be evaluated within 30 minutes of collection; if impossible, store at 4°C until analysis.
Coagulation Abnormalities
- Coagulation abnormalities can lead to extensive hemorrhaging.
