What Happens to Your Blood?

Registration The registration process is the initial step. Here, we confirm your identity by asking for your Kaiser identification card and a photo identification card. This is very important so that the proper specimen labels and accordingly the proper tests are performed and reported to the correct patient. A registration process must be performed when you submit the sample to the laboratory, the sample cannot be dropped-off without this process.
Collection
It all starts with the collection of a proper blood or other specimen. A doctor, nurse, technician, or phlebotomist will draw your blood. Several tubes of blood may need to be drawn for different types of tests.
Depending on your condition, your doctor may want to obtain urine, a throat swab, or other sample. Follow the directions carefully; the right sample leads to the right answers.
After the sample is collected, the container is always labeled with your name and other information. If you're bringing a sample to the lab, make sure that it has your name and medical number on it so that we do the proper tests and report them on the right patient.
Processing
When the sample gets to the laboratory, it's logged into the hospital computer. In some cases the liquid portion of blood is separated from the cells to prepare it for testing. It's then given to the laboratory staff who will perform the testing.
Testing
In the Chemistry section of the lab, blood and other body fluids are tested for chemicals, drugs, and substances that indicate disease. Examples of Chemistry tests include cholesterol and other tests for risk of heart disease, glucose to monitor diabetes, digoxin to help the providers give the correct dose of this powerful drug, and thyroxin to monitor the function of the thyroid gland. The Hematology section of the lab analyzes the amount and function of blood cells and plasma. Examples of Hematology tests include the Complete Blood Count (CBC) that tells the doctor how many cells of each type are in your blood, and the prothrombin time (PT), used to monitor patients on the drug Coumadin. The Microbiology section of the lab tests patients for infection with bacteria, fungi, and parasites. Many types of specimen including blood, urine, sputum, stool, and others are tested. An example of a Microbiology test is a urine culture for urinary tract infections. The Virology laboratory tests for viral infections. Depending on the virus suspected, the laboratory might look for the virus directly, or test your blood to see if your immune system has reacted to a virus. Examples of Virology tests include rapid antigen test for influenza and HIV antibody tests. The Immunology/Molecular Diagnostics laboratory performs a wide variety of complex tests. Some tests are used by your doctor to determine whether your immune system is functioning properly. State-of-the-art analysis of DNA and RNA is used to test for a variety of diseases. Other specialized tests include the ANA, used to screen for autoimmune disease, and Factor V Leiden
