Blood Tests FAQ
What is a blood test used for?
Blood tests can be used to assess your health, as well as help your doctor diagnose or monitor a range of conditions. See this blood testing guide for general information and to understand what’s involved.
What does a blood test show?
Ammonia levels: Blood tests will show the amount of ammonia in your blood. High ammonia levels may be a sign of liver and kidney damage. Blood alcohol content (BAC): This test measures the amount of alcohol in your system. Ferritin: You may have a ferritin test if your CBC tests show you don’t have enough iron. When should I have a blood test?
What is a blood type test?
Your blood type is one of the things that can be measured with a blood test. Blood type is designated by two types of markers—the ABO type and the Rh type. A blood typing test detects the presence or absence of these markers. The plus sign indicates Rh markers, while the minus sign indicates Rh-negative. All these blood types are perfectly healthy.
What does a blood test look for?
In many cases, blood tests are used to confirm that your health is good. Interpreting blood tests is best left to a physician, but it may be helpful to know what a test looks for. This article breaks down common blood tests and explains what they mean.
How does a blood test work?
A needle will then be inserted into a vein in your arm. A small amount of blood is collected and put into one or more tubes and sent to a pathology service for analysis. After the needle is removed, you'll need to keep pressure on the site where the blood was taken for a short while. Try not to use that arm too much for the rest of the day.
