In medical terminology, what does "-emia" refer to?

The suffix "-emia" is derived from Greek and refers specifically to a condition related to the blood. It is often used in medical terminology to indicate the presence of a particular substance or condition within the blood. For example, "anemia" refers to a deficiency of red blood cells or hemoglobin, while "hyperglycemia" indicates elevated levels of glucose in the blood. This suffix emphasizes the relationship or condition concerning blood, making it integral to various medical diagnoses and discussions.

In contrast, the other choices do not align with the meaning of "-emia." Examination relates to the process of checking or evaluating, disease refers to a pathological condition affecting the body, and puncture denotes an action describing piercing or penetrating a surface. Each of these terms holds its distinct definition and use in medical vocabulary but does not connect to the concept attributed to "-emia."
