When Does the Term ‘Blood Dyscrasias’ Get Used in Medicine?

Blood dyscrasias are hematologic disorders affecting the cellular or plasma components of the blood, including the bone marrow and the lymph tissue. Examples of the diseases include anemia, leukemia, and lymphoma. However, due to unfamiliarity with the term, people do not often recognize it at first glance. But when does the term blood dyscrasias get used in medicine? Here are some ideas.

1. Describing Blood Disorders

If you want to describe blood disorders, you are most likely using blood dyscrasias as a medical term. Generally, physicians use the term blood dyscrasias when describing these kinds of problems while breaking down its various causes into various categories.

One of the most important categories is the blood cell line. Blood dyscrasias are often grouped into three main categories, including:

a. Acute.

Acute blood dyscrasia consists of rapidly growing cells that are short-lived, such as leukemia.

b. Chronic.

Chronic blood dyscrasia includes cancers that develop slowly and progress over time.

c. Infectious. 

Infectious blood dyscrasia includes viral infections like hepatitis and HIV.

Other categories include platelet disorders, abnormalities of the blood vessels, and the number of typical blood components. When describing blood disorders, the term blood dyscrasias is generally used in a medical setting.

2. Uncertain Diagnosis

The term blood dyscrasias are also helpful in describing an uncertain diagnosis. There are several types of blood abnormalities that all fall under the blood dyscrasias umbrella.

For instance, if you have certain kinds of anemia, such as iron deficiency anemia, you may have low levels of red blood cells, white blood cells, and platelets. You may have abnormal bleeding if you have a bleeding disorder, such as hemophilia.

Blood dyscrasias are also helpful for describing patients with symptoms that are not easily categorized. For instance, if you have anemia but it does not fall into the specific categories, you may have blood dyscrasia.

3. In the Presence of Risk Factors

Blood dyscrasias are also used to describe patients with certain risk factors. For example, blood dyscrasias can develop if you have specific genetic abnormalities. Other risk factors include certain medications, diseases, and other factors.

By definition, blood dyscrasias are disorders of the blood. The word dyscrasias is a medical term for an abnormality of a healthy state. So, when a person has blood dyscrasia, it is an abnormality of the normal process of blood function.

4. Specific Concerns

Overall, blood dyscrasias can refer to a variety of different problems. However, a person can have the symptoms or issues related to the disorders but not have the condition itself. Sometimes, the person may have a disease but not experience any symptoms.

In other cases, a person may have problems related to the disorder but not have a blood dyscrasia. For example, if you have a blood disorder, such as sickle-cell anemia, you may experience symptoms. On the other hand, if you have a blood disorder but not sickle-cell anemia, then you do not have blood dyscrasia.

For this reason, it is essential to remember that blood dyscrasias are both a term and quality of blood disorders. A blood dyscrasia is a blood abnormality that does not always result in symptoms or problems.


In summary, blood dyscrasias are disorders of cell and blood components in the body – blood cells, red blood cells, white blood cells, and platelets. These blood disorders are often grouped into three main categories: acute, chronic, and infectious. However, the term also serves another essential purpose: helping to describe an uncertain diagnosis.

You may have a blood dyscrasia with specific symptoms, but medical experts can’t determine the cause. Therefore, the next time you hear the term blood dyscrasias, remember that it refers to a blood disorder. As a term, it helps describe blood disorders, some of which have symptoms while others do not.
