Your evaluation may include the performance of specific blood tests, including (but not limited to) cell counts, measurement of various blood chemistries and markers of inflammation. We can measure many things in your blood such as salts, blood cell counts and protein markers specific to the heart (one is called BNP). Additional tests may include blood chemistries, evaluation of liver and kidney functions, and genetic studies). In some cases, genetic testing may be recommended. In addition, we may ask you to join our ongoing studies by allowing us to collect and store some of your blood for future analysis.
Complete Blood Count (CBC)
A complete blood count (CBC) measures the size, number, and maturity of the different blood cells in a specific volume of blood. This is one of the most common tests performed.
Red blood cells are important for carrying oxygen and fighting anemia and fatigue. The hemoglobin portion of the CBC measures the oxygen carrying capacity of the red blood cells while the hematocrit measures the percentage of red blood cells in the blood.
White blood cells fight infection. Increased numbers of white blood cells, therefore, may indicate the presence of an infection. Decreased levels may indicate certain rheumatic diseases or reaction to medication.
Platelets prevent the body from bleeding and bruising easily. It is usually performed to check for a blood infection.
During a CBC, a sample of blood is drawn and checked for the following:
The number of red blood cells, white blood cells, and platelets
The amount of hemoglobin (the protein that carries oxygen) in the red blood cells
The portion of the blood sample made up of red blood cells
Blood Chemistry Study
A blood chemistry study is a procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that makes it.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
