What happens during a Legionella test?
Legionella tests may be done in urine, sputum, or blood.
During a urine test:
You will need to use the "clean catch" method to ensure your sample is sterile. The clean catch method includes the following steps:
Wash your hands.
Clean your genital area with a cleansing pad.
Start to urinate into the toilet.
Move the collection container under your urine stream.
Collect at least an ounce or two of urine into the container, which should have markings to indicate the amount.
Finish urinating into the toilet.
Return the sample container as instructed by your health care provider.
Sputum is a thick type of mucus made in your lungs when you have an infection. 
During a sputum test:
A health care provider will ask you to breathe deeply and then cough deeply into a special cup.
Your provider may tap you on the chest to help loosen sputum from your lungs.
If you have trouble coughing up enough sputum, your provider may ask you to breathe in a salty mist that can help you cough more deeply.
During a blood test:
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
