Dr. Nabili received his undergraduate degree from the University of California, San Diego (UCSD), majoring in chemistry and biochemistry. He then completed his graduate degree at the University of California, Los Angeles (UCLA). His graduate training included a specialized fellowship in public health where his research focused on environmental health and health-care delivery and management.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
The complete blood count (CBC) is one of the most commonly ordered blood tests. The complete blood count is the calculation of the cellular (formed elements) of blood. These calculations are generally determined by special machines that analyze the different components of blood in less than a minute.
A major portion of the complete blood count is the measure of the concentration of white blood cells, red blood cells, and platelets in the blood.
How is the complete blood count test (CBC) done?
The complete blood count (CBC) test is performed by obtaining a few milliliters (one to two teaspoons) of blood sample directly form the patient. It can be done in many settings including the doctor's office, laboratories, and hospitals. The skin is wiped clean with an alcohol pad, and a needle is inserted through the area of cleansed skin into to patient's vein (one that can be visualized from the skin.) The blood is pulled from the needle by a syringe or by a connection to a special vacuumed vial where it is collected. This sample is taken to the laboratory for analysis.

Viewer Question: What are some of the potential diagnoses when a person has a high platelet count? (Platelet count approximately 420?)
Dr. Stöppler's Response: Platelets are the smallest cell-like structures in the bloodand are important for blood clotting and plugging damaged blood vessels.
Platelet countsare usually done by laboratory machines that also count other blood elements such as the white and red cells. Normal platelet counts are in the range of 150,000 to 400,000 per microliter (or 150 - 400 x 109 per liter), but the normal rangefor the platelet count varies slightly among different laboratories.
Multiple myeloma is often referred to simply as myeloma. It is a type of cancer that starts in the plasma cells of the bone marrow. These are protein-making cells which normally make all of the different kinds "...
