Skin test; candida
CPT4 code
Name of the Procedure:
Skin Test for Candida
Common Names: Candida Skin Test, Candida Antigen Test.
Summary
A candida skin test is a diagnostic procedure in which a small amount of candida antigen is injected into the skin to assess the immune system's reaction. It is typically used to check for a delayed-type hypersensitivity reaction, which indicates the presence of a functioning immune system.
Purpose
Addresses: This procedure helps in identifying whether an individual's immune system is capable of responding to fungal infections, specifically those caused by Candida species. Goals/Expected Outcomes: A positive reaction implies a healthy immune response, while a negative reaction may indicate an immune deficiency that requires further investigation.
Indications
Symptoms or Conditions:
- Recurrent or chronic fungal infections
- Assessment of cell-mediated immunity Patient Criteria: Patients with suspected immune system deficiencies, particularly in cases of recurrent fungal infections or to monitor immunosuppressive therapies.
Preparation
Pre-procedure Instructions: Patients may be advised to avoid antihistamines and certain medications that could interfere with skin test results. Ensure the skin area for the test is clean and free from creams or lotions. Diagnostic Tests/Assessments: No specific tests are typically needed beforehand, but a thorough medical history and review of current medications are essential.
Procedure Description
- A small amount of candida antigen is selected and prepared.
- The injection site, often the forearm, is cleaned with an antiseptic.
- Using a small needle, the healthcare provider injects a minute quantity of the candida antigen just beneath the skin's surface.
- The injection site is monitored for signs of a reaction, such as redness, swelling, and induration (hardening).
Tools and Equipment: Small syringe, candida antigen solution, antiseptic swabs. Anesthesia/Sedation: Generally, no anesthesia or sedation is needed as it is a minimally invasive procedure.
Duration
The injection process takes only a few minutes. The reaction is typically evaluated within 48 to 72 hours.
Setting
The procedure is usually performed in an outpatient clinic or a physician's office.
Personnel
This test is typically administered by a healthcare provider, such as a nurse or physician.
Risks and Complications
Common Risks: Mild pain or discomfort at the injection site, minor swelling, or redness. Rare Risks: Severe allergic reactions (though extremely rare), infection at the injection site. Management: Ensure that emergency equipment and antihistamines are available to manage any unexpected reactions.
Benefits
A properly functioning immune response can be verified quickly and non-invasively. Results are often available in a few days, allowing for timely medical decisions.
Recovery
Post-procedure Care: Monitor the injection site for any signs of infection or unusual reactions. Follow any specific instructions provided by the healthcare provider. Recovery Time: No downtime is required; patients can resume normal activities immediately. Follow-up: Return to the clinic after 48-72 hours for evaluation of the test site.
Alternatives
Others: Blood tests to measure specific immune markers, different types of skin tests using other antigens. Pros and Cons: Blood tests can provide broader information about the immune system but may be more invasive and costly.
Patient Experience
During: Patients may feel a slight sting or discomfort during the injection. After: Some local tenderness or mild itching may occur at the test site. Pain Management and Comfort Measures: Over-the-counter pain relievers or cold compresses can alleviate discomfort if needed.
