Allergy Testing in-house for Pediatric Office

As the stress from COVID is starting to fade away, we are eager to get into other stressful things!! We realize that our office is not doing in-house allergy testing. We normally sent out for lab work or refer the patient to an allergist. We appreciate any input from practices that are doing the test. Is it worth it in terms of investment? How is the Insurance treating you? Are you adding treatment with injections to the mix?
Appreciate any input!
