Hematology is the branch of medicine focused on the study of blood, blood-forming organs, and related disorders. It includes the diagnosis and treatment of conditions such as:
Hematologists use specialized tests like complete blood counts (CBC) and bone marrow analysis to provide accurate diagnoses and effective treatments.
Sickle beta zero thalassemia is a complex genetic disorder resulting from the inheritance of two specific hemoglobinopathies: This condition manifests as a severe form of anemia, characterized by the coexistence of sickle hemoglobin (HbS) and the absence of beta-globin chain production. It is one of the more severe forms of sickle cell disease (SCD), leading … Read more
Hemoglobin plays a critical role in maintaining blood pH within a narrow range, acting as an effective buffer system. Blood pH is tightly regulated around 7.35–7.45, and even small deviations can impair cellular functions. Its buffering capacity is due to its ability to bind to hydrogen ions (H⁺) and carbon dioxide (CO₂), both of which … Read more
Hemoglobin is a vital protein in red blood cells responsible for transporting oxygen from the lungs to tissues and carrying carbon dioxide back to the lungs for exhalation. While most people are familiar with adult hemoglobin (HbA), the human body also produces a distinct form called fetal hemoglobin (HbF) during fetal development. Here’s the key … Read more

Platelets are small fragments play an indispensable role in maintaining hemostasis,blood clotting. They also known as thrombocytes, are miniature cellular powerhouses essential for blood clotting. Its primary mission is to prevent excessive bleeding by forming clots at the site of vascular injuries, sealing wounds and maintaining the integrity of the circulatory system. Medical Interventions in … Read more
Mchc meaning is Mean Corpuscular Hemoglobin Concentration. It represents the average concentration of hemoglobin in a given volume of red blood cells. एमसीएचसी, या मीन कॉर्पस्क्यूलर हीमोग्लोबिन एकाग्रता, लाल रक्त कोशिकाओं की एक निश्चित मात्रा में हीमोग्लोबिन की औसत एकाग्रता का प्रतिनिधित्व करता है। Monitoring MCHC levels helps evaluate the oxygen-carrying capacity of red blood … Read more
The MPV blood test (Mean Platelet Volume) measures the average size of platelets in the blood. Mpv blood test principle The principle involves analyzing the volume of platelets present and calculating the mean or average size. Mpv blood test procedure Mpv test Results Interpretation Mean Platelet Volume High means Mean Platelet Volume low means Here … Read more
Giemsa stain is a histological and cytological stain. It is commonly used in laboratories. The stain enhances the visibility of components. It is especially useful in blood smears and bone marrow samples. Giemsa stain principle The Giemsa stain uses a mixture of dyes. These dyes selectively stain cellular components. This technique aids in the visualization … Read more
The ESR (erythrocyte sedimentation rate) test is a simple blood test that measures the rate at which red blood cells settle at the bottom of a tube over a specific time. It is a non-specific test that helps to detect inflammation in the body. ESR test principle The ESR test is based on the principle … Read more
A nuclear stress test without a treadmill is called a pharmacological or chemical stress test. This is used for individuals who are unable to exercise adequately on a treadmill due to physical limitations or other health concerns. Nuclear stress test procedure phases 1. Nuclear stress test preparation Before the test, you should avoid caffeine-containing products … Read more
