Antibody; fungus, not elsewhere specified

CPT4 code

Name of the Procedure:

Antibody; fungus, not elsewhere specified


The test measures specific antibodies in the blood to identify a fungal infection. Antibodies are proteins made by the immune system in response to the presence of a foreign substance, such as a specific fungus.


This procedure is used to diagnose infections caused by fungi that are not typically specified in standard fungal tests. It helps in identifying unusual or rare fungal infections when common tests fail. The goal is to provide accurate diagnosis and guidance for appropriate treatment.


  • Persistent, unexplained symptoms of infection (e.g., fever, fatigue).
  • Unresponsive to typical antibacterial treatments.
  • Immunocompromised patients prone to fungal infections.
  • History of exposure to environments with high fungal presence.


  • No special preparation is usually needed.
  • Inform the doctor about any medications or supplements being taken.
  • Undergo any recommended blood tests to ensure good health prior to the antibody test.

Procedure Description

  1. Blood Sample Collection:
    • A healthcare professional will clean the area on the arm.
    • A small needle is used to draw blood from a vein.
    • The blood sample is collected in a vial or tube.
  2. Laboratory Analysis:
    • The blood sample is analyzed in a laboratory to detect specific antifungal antibodies.
  3. Results:
    • Results are interpreted by a doctor, who will discuss them and decide the next steps.


The blood draw itself takes about 5-10 minutes. Lab results can take several days to a week.


The procedure is performed in a hospital, outpatient clinic, or a specialized diagnostic lab.


  • Phlebotomist or Nurse (for blood draw)
  • Medical Laboratory Technician (for sample analysis)
  • Physician or Infectious Disease Specialist (for diagnosis and interpretation)

Risks and Complications

  • Minor bruising or bleeding at the puncture site.
  • Rare risk of infection at puncture site.
  • Fainting or dizziness may occur for some during blood draw.


  • Accurate identification of fungal infections that are otherwise difficult to diagnose.
  • Facilitates targeted treatment, improving patient outcomes.
  • Helps prevent inappropriate use of broad-spectrum antibiotics.


  • Immediate recovery from blood draw.
  • Normal activities can be resumed right after the procedure.


  • Other fungal culture tests, though they may take longer to yield results.
  • Imaging scans (like X-rays or CT scans) to detect fungal growth, but these are less specific.
  • DNA-based fungal tests that identify genetic material of fungi but may be more expensive.

Patient Experience

  • A slight pinch or sting during blood draw.
  • Possible mild discomfort at the puncture site.
  • Generally minimal pain or discomfort afterwards. Managing the puncture site with gentle pressure and a bandage can alleviate mild irritation.

Pain management: Typically unnecessary, but mild pain relievers can be used if there is discomfort post-procedure.
