Aspergillosis Precipitin

Alternate Names : Aspergillosis Precipitin

Overview & Description | Preparation & Expectations | Results and Values

Aspergillosis precipitin is a blood test that detects antibodies against a common fungus, or mold, called Aspergillus. The aspergillosis infection spreads in the bloodstream. It may cause an infection in the ear, cornea of the eye, heart valves, sinuses, lungs or brain.

Who is a candidate for the test?

This test is normally performed to detect and diagnose a particular fungal infection. This test may be done on a person who has symptoms similar to symptoms of pneumonia or tuberculosis with a history of:

  • chest pain
  • shortness of breath
  • wheezing
  • coughing up thick or blood tinged mucous
  • It may also be done on a person with clouded vision, eye pain, and reddened eyes.

    How is the test performed?

    A blood sample is taken from a vein on the forearm or hand. First, the skin over the vein is cleaned with an antiseptic. Next, a strong rubber tube, or tourniquet, is wrapped around the upper arm. That enlarges the veins in the lower arm by restricting blood flow through them.

    A fine needle is gently inserted into a vein and the rubber tube is removed. Blood flows through the needle and is collected in a syringe or vial for testing in the lab. After the needle is withdrawn, the puncture site is covered for a short time to prevent bleeding.
