Study Notes
Complete Blood Count (CBC)
- A complete blood count (CBC) provides information about a person's blood, including the number of different blood cells, their size and shape, and other characteristics.
- It measures various components, such as hemoglobin, hematocrit, red blood cell count, white blood cell count, and platelet count.
Red Blood Cell Indices
- Red blood cell indices indicate the size and hemoglobin content of red blood cells, which can help diagnose anemia, a condition characterized by a lack of red blood cells or hemoglobin.
- The indices include mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC).
White Blood Cell Differential
- A white blood cell differential is a component of a CBC that identifies the different types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
- This information helps diagnose infections, allergies, and inflammatory diseases.
Medical Assessment
- A CBC is a useful diagnostic tool in medical assessment, helping healthcare professionals diagnose and monitor various blood disorders, such as anemia, infection, and blood cancer.
- It can also aid in monitoring the effectiveness of treatment and detecting potential complications.
Interpreting CBC Results
- CBC results are interpreted by comparing them to a reference range, which is a set of values that are considered normal for a particular population.
- Abnormal results can indicate a range of conditions, including anemia, infection, inflammation, and blood cancer.
Flow Cytometry
- Flow cytometry is a laboratory technique used to detect and measure the characteristics of cells or particles, such as size, shape, and surface proteins.
- It is commonly used to diagnose and monitor blood cancers, such as leukemia and lymphoma.
Preparing Cells for Analysis
- Cells or particles are prepared for analysis in flow cytometry by suspending them in a fluid and passing them through a specialized instrument.
- The instrument uses a laser to detect and measure the characteristics of the cells or particles.
Fluorescent Markers
- Fluorescent markers are used in flow cytometry to label specific cells or proteins, allowing them to be detected and measured.
- These markers emit a fluorescent signal when excited by a laser, which is then detected by the instrument.
Common Uses of Flow Cytometry
- Flow cytometry is commonly used in cancer diagnosis and monitoring, as well as in immunology and infectious disease research.
- It is also used to evaluate the effectiveness of stem cell transplantation and to detect minimal residual disease.
Cell Analysis Capacity
- Flow cytometry can quickly examine an approximate number of 10,000 to 30,000 cells per second.
