When a small sample of tissue is taken from the body and sent to a clinical laboratory to be examined or studied, it is called a biopsy. Biopsies are performed to diagnose diseases, such as cancer, by analyzing tissue samples under a microscope. This procedure provides critical information about the presence and extent of diseases.

Hypertensionis the medical term for high blood pressure. It is a condition where the force of the blood against the artery walls is consistently too high, which can lead to heart disease, stroke, and other health problems. The other terms refer to different conditions:

Hyperemia: Increased blood flow to a particular area of the body.

Hypertrophy: Enlargement of an organ or tissue from the increase in the size of its cells.

Hyperthermia: Abnormally high body temperature.

When a venipuncture is performed using a lavender top vacutainer tube, the sample is commonly used for hematology testing, such as complete blood counts (CBC). The lavender top tube contains an anticoagulant called EDTA (ethylenediaminetetraacetic acid), which prevents the blood from clotting. This allows for the preservation of the cellular components of the blood for accurate hematological analysis.
