What is CBC Test?

A CBC test is a hematology test that examines the number and quality of red blood cells, white blood cells, and platelets in a blood sample. This test provides valuable information about a person’s overall health, including any potential diseases or disorders within their body. The purpose of the CBC test is to detect any irregularities with these blood components, leading to early diagnosis and treatment.

The CBC tube colors used for this type of test include lavender, green, and light blue. Lavender tubes are used to collect whole blood samples for automated cell counters. Green tubes are used for plasma separation and testing electrolyte levels, while light blue tubes contain sodium citrate to prevent clotting during coagulation testing.

The correct order of draw for CBC tube colors is important to obtain accurate results. The first step is to collect a discard tube; this will clear out any residual anticoagulants from previous collections. Next, lavender tubes are collected followed by the green and then the light blue tube.

To collect a sample from a CBC blood tube, one must first prepare the patient by explaining each step involved in obtaining their blood sample. Following that, they locate an appropriate site on the arm where they wipe with an antiseptic solution before inserting a venipuncture needle into the vein until they notice adequate amounts of blood flowing into the collection tube.

By understanding what CBC tests are and how they work, it becomes easier to grasp why many healthcare providers recommend them concerned patients or those seeking overall good health but unsure if there may be underlying medical conditions that could affect their wellbeing. Therefore, everyone should consult their doctor at least once annually concerning undergoing basic health screenings like CBC tests since prevention is always better than cure.

Your blood count speaks volumes about your medical diagnosis, as long as it falls within the reference range.

Purpose of CBC Test

CBC Test: Understanding Its Purpose in Medical Diagnosis

A CBC test is a common blood count performed during medical diagnosis. It analyzes the three types of blood cells – red blood cells, white blood cells, and platelets, to screen for abnormalities.
