What is this test?

This laboratory code appears to refer to a qualitative test that has been deprecated. The compressed code does not reliably identify the analyte, specimen, or testing method.

Why might I need this test?

A qualitative test reports whether a substance or condition is detected rather than providing a measured concentration. The clinical reason for ordering this deprecated test cannot be determined from the code alone.

How is the test performed?

The laboratory analyzes a patient specimen using an established method. Because the specimen and method are not identifiable from this code, the laboratory report should be used to confirm the procedure that was performed.

How do I prepare for the test?

Preparation depends on the specimen and test involved. Follow the instructions provided by the ordering clinician or laboratory, and ask for the current test name if you are considering repeat testing.

Reference range

Adult: 10-40 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Frequently asked questions

What does this test measure?
The analyte cannot be reliably decoded from this code. It appears to be a qualitative test, meaning it generally reports detected or not detected rather than a numeric concentration.
Does this code specify the required specimen?
No reliable specimen can be identified from the code. Confirm whether the test used blood, serum, urine, stool, or another sample with the laboratory.
Why was the test marked as deprecated?
Deprecated codes may represent an older testing method, an obsolete analyte, or a test replaced by a newer procedure. The laboratory can determine whether the result remains clinically useful.
