What is this test?
The Health Leads Screening Panel is a collection of laboratory tests used to look for selected substances, exposures, or health markers. Because the slug does not identify the individual analytes, check your requisition or online results for the exact tests included.
Why might I need this test?
A clinician may order this panel when evaluating possible exposure to environmental substances, monitoring nutritional or metabolic factors, or investigating nonspecific symptoms. The reason for testing depends on the specific substances included in the panel.
How is the test performed?
A laboratory analyzes a specimen using methods appropriate for each substance in the panel. The required specimen and any special collection instructions should be shown on the order; common options may include blood, serum, plasma, or urine.
How do I prepare for the test?
Follow the preparation instructions provided with your order. They may specify fasting, timing, medication or supplement restrictions, and how to collect the specimen. If instructions are unclear, contact the ordering clinician or laboratory before testing.
Reference range
Adult males: 7-56 U/L; Adult females: 7-43 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An abnormal result may suggest exposure to a substance, a nutritional or metabolic imbalance, or another condition associated with the marker being tested. Some results may also be affected by recent diet, supplements, medications, or other exposures. A healthcare professional should interpret each result in your medical context and decide whether follow-up testing is needed.
