STATION ONE: Blood Analysis in Hematology Lab

  • Equipment Identification

    • Name of Equipment: The equipment is known as a hematology analyzer.

    • Use in Hematology Lab: A hematology analyzer is used to perform automated complete blood counts (CBC) and analyze the overall health of blood cells. It provides information on the number and types of blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets, which are essential for diagnosing various medical conditions.

  • Components of Blood Observed

    • Red Blood Cells (RBCs)

    • White Blood Cells (WBCs)

    • Platelets

    • Hemoglobin Levels

    • Hematocrit Percentage

STATION TWO: Tumor Classification

  • Tumor Description

    • A tumor is an abnormal mass of tissue that results from excessive cell division. Tumors can be classified as either benign or malignant based on their characteristics and behavior.

  • Differentiating Benign and Malignant Tumors

    • Benign Tumors:

    • Non-cancerous growths

    • Typically well-defined, encapsulated, and do not invade nearby tissues

    • Slow growth rate

    • Generally do not metastasize (spread to other parts of the body)

    • Malignant Tumors:

    • Cancerous growths

    • Irregularly shaped, poorly defined borders, and invade surrounding tissues

    • Rapid growth rate

    • Capable of metastasis

  • Examples of Tumors

    • Benign Tumors:

    1. Lipoma (fatty tumor)

    2. Adenoma (glandular tumor)

    • Malignant Tumors:

    1. Carcinoma (cancer of epithelial tissue)

    2. Sarcoma (cancer of connective tissues)

STATION THREE: Complete Blood Count Results

  • Reasons for Carrying Out a Complete Blood Count (CBC)

    1. To evaluate overall health and detect a variety of disorders such as anemia, infection, and leukemia.

    2. To monitor a medical condition such as a disease or treatment (e.g., chemotherapy).

    3. To assess blood loss or iron deficiency.

  • Abnormalities Presented by Results

    1. Low Hemoglobin level

    2. Low Hematocrit level

    3. Elevated White Blood Cell count

    4. Decreased Platelet count

    5. Presence of abnormal cells (e.g., blast cells in case of leukemia)

  • Working Diagnosis (es)

    1. Anemia

    2. Possible Hematologic Malignancy (e.g., leukemia)

STATION FOUR: Wound Healing

  • Definition of Wound Healing

    • Wound healing is the biological process by which the body repairs and regenerates damaged tissue following injury. It involves a complex series of events, including hemostasis, inflammation, proliferation, and remodeling.

  • Difference Between Acute and Chronic Wounds

    • Acute Wounds:

    • Wounds that heal in a timely manner, typically within weeks

    • Usually result from a specific injury or surgical procedure

    • Examples include cuts, abrasions, and surgical incisions

    • Chronic Wounds:

    • Wounds that do not heal as expected and can persist for months or years

    • Often associated with underlying health conditions such as diabetes or poor circulation

    • Examples include pressure ulcers and diabetic foot ulcers

  • Factors Affecting Healthy Healing of Wound

    • 1. Infection: Presence of pathogens can impede the healing process, leading to prolonged inflammation and tissue damage.

    • 2. Poor Blood Supply: Insufficient circulation can reduce the delivery of oxygen and nutrients critical for tissue repair.

    • 3. Underlying Medical Conditions: Chronic diseases like diabetes or conditions that affect immunity can significantly delay the healing process.
