In general, it is a non-specific term that can refer to any blood-related disease. That said, it tends to be used when a diagnosis is uncertain (during diagnosis) or in specific situations.

Blood dyscrasias are medical conditions (hematologic disorders) that may affect the cellular or plasma components of the blood, the bone marrow, or the lymph tissue. Examples of blood dyscrasias include anemias, cancers such as leukemias and lymphomas, conditions that cause the blood to clot or bleed too readily, and more.

Blood dyscrasias may be common or uncommon, malignant (cancerous) or benign, and range from conditions that are very mild or asymptomatic, to those that are life-threatening. We will look at causes or mechanisms responsible for blood dyscrasias, the different types, common symptoms, and what you may expect when it comes to diagnosis and treatment.
