2. RBC(Red Blood Cell), Hb(Hemoglobin), Hct(Hematocrit), MCV(Mean corpuscular volume), MCH(Mean corpuscular Hb), RDW(Red cell Distribution width)
Red blood cells (RBCs), also known as erythrocytes, are responsible for carrying oxygen throughout the body. Hemoglobin (Hb) is the iron-rich protein within RBCs that binds to and transports oxygen. Hematocrit (Hct) measures the percentage of RBCs in the total blood volume. MCV (Mean Corpuscular Volume) and MCH (Mean Corpuscular Hemoglobin) provide information about the size and hemoglobin content of RBCs, respectively. RDW (Red cell Distribution Width) measures the variation in RBC size. Together, these parameters provide a comprehensive assessment of the red blood cell population and can help diagnose and monitor various conditions, such as anemia, polycythemia, and thalassemia. Maintaining healthy levels of these red blood cell-related markers is crucial for ensuring adequate oxygen delivery to the body's tissues and organs.

3. Plt(Platelet)
Platelets, also known as thrombocytes, are small cell fragments that play a vital role in blood clotting and hemostasis. They are responsible for initiating the clotting process, which helps stop bleeding and prevent excessive blood loss. Platelet counts can provide valuable information about an individual's overall health and risk of bleeding or clotting disorders. Low platelet counts (thrombocytopenia) can lead to increased bleeding, while high platelet counts (thrombocytosis) can increase the risk of blood clots. Monitoring platelet levels is essential for the diagnosis and management of various hematological conditions, such as immune thrombocytopenic purpura (ITP), leukemia, and myeloproliferative disorders. Maintaining a healthy platelet count is crucial for maintaining proper blood clotting and preventing potentially life-threatening complications.

4. Seg. Neutrophil, Lymphocyte, Monocyte, Eosinophil, Basophil
The different types of white blood cells, including segmented neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each have specialized functions in the body's immune response. Segmented neutrophils are the most abundant type of white blood cells and are the first responders to sites of infection or inflammation. Lymphocytes, such as T cells and B cells, play a crucial role in adaptive immunity and the recognition of specific pathogens. Monocytes can differentiate into macrophages and dendritic cells, which are involved in phagocytosis and antigen presentation. Eosinophils are associated with allergic reactions and parasitic infections, while basophils are involved in the inflammatory response. Monitoring the levels and ratios of these different white blood cell types can provide valuable insights into the body's immune status and help in the diagnosis and management of various medical conditions, such as infections, autoimmune disorders, and certain types of cancer.

5. ESR(Erythrocyte Sedimentation Rate)
The Erythrocyte Sedimentation Rate (ESR) is a simple blood test that measures the rate at which red blood cells (erythrocytes) settle to the bottom of a test tube. This rate can provide information about the presence of inflammation or infection in the body. Elevated ESR levels are often associated with conditions such as rheumatoid arthritis, lupus, cancer, and certain infections. However, it is important to note that ESR is a non-specific marker, and its interpretation should be done in the context of the patient's clinical presentation and other laboratory findings. While ESR can be a useful tool in the diagnostic process, it should not be used in isolation but rather as part of a comprehensive evaluation to help identify the underlying cause of the inflammation or disease.

6. Reticulocyte count
The reticulocyte count is a measure of the number of immature red blood cells (reticulocytes) in the blood. Reticulocytes are the precursors to mature red blood cells and are released from the bone marrow into the bloodstream. An elevated reticulocyte count can indicate increased red blood cell production, which may be a sign of anemia, blood loss, or other conditions that stimulate the bone marrow to produce more red blood cells. Conversely, a low reticulocyte count can suggest a problem with red blood cell production, such as in cases of aplastic anemia or certain types of leukemia. Monitoring the reticulocyte count, along with other red blood cell parameters, can provide valuable insights into the body's erythropoietic (red blood cell production) activity and help in the diagnosis and management of various hematological disorders.

7. 혈액 응고 검사
Blood coagulation tests are a group of laboratory tests that evaluate the body's ability to form and dissolve blood clots. These tests include prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR), among others. They provide information about the function of the various clotting factors and the overall coagulation cascade. Abnormal results in these tests can indicate an increased risk of bleeding or excessive clotting, which may be associated with conditions such as liver disease, vitamin K deficiency, hemophilia, or thrombophilia. Monitoring coagulation parameters is crucial for the management of patients on anticoagulant therapy, as well as for the diagnosis and treatment of various hematological and cardiovascular disorders. Proper interpretation of these test results, in conjunction with the patient's clinical history and other laboratory findings, is essential for effective clinical decision-making.

Urinalysis, or urine analysis, is a comprehensive examination of the physical, chemical, and microscopic properties of urine. It is a valuable tool in the diagnosis and monitoring of various medical conditions, as the composition of urine can provide insights into the health of the kidneys, urinary tract, and overall metabolic processes. Urinalysis can detect the presence of proteins, glucose, blood, bacteria, and other substances that may indicate the presence of conditions such as kidney disease, diabetes, urinary tract infections, or even certain types of cancer. Additionally, the microscopic examination of urine sediment can reveal the presence of cells, casts, and crystals that can further aid in the diagnosis and management of various renal and urological disorders. Regular urinalysis, along with other laboratory tests and clinical assessments, is an essential component of comprehensive healthcare and can help healthcare providers make informed decisions about patient care.
