What happens during a synovial fluid analysis?
Your synovial fluid will be collected in a procedure called arthrocentesis, also known as joint aspiration. During the procedure:
A health care provider will clean the skin on and around the affected joint.
The provider will inject an anesthetic and/or apply a numbing cream to the skin, so you won't feel any pain during the procedure. If your child is getting the procedure, he or she may also be given a sedative. Sedatives are medicines that have a calming effect and help reduce anxiety.
Once the needle is in place, your provider will withdraw a sample of synovial fluid and collect it in the syringe of the needle.
Your provider will put a small bandage on the spot where the needle was inserted.
The procedure usually takes less than two minutes.
