On-site Laboratory

State of the art

on-site laboratory

After our surgeon has taken the first cancerous tissue layer, the doctor prepares the tissue for the laboratory. The lab technician freezes the tissues and cuts thin horizontal slices in the tissue. The slices are placed on microscopic slides, stained, and covered.  This process is time-consuming because it is critical to ensuring the removal of all cancer tissue.

Immediate Results

After the tissue has been prepared, our surgeon examines the undersides and edges of the tissue on the slides using a high-power microscope. If our surgeon finds no remaining cancer cells,  you will either be prepared for surgical reconstruction or for the wound to be bandaged and self-heal. 

However, if our surgeon does find any remaining cancer cells, it is marked on the surgical site map. You will be brought back into a room to be numbed for another layer of cancer tissue to be removed.

Dermatology Laboratory FAQs

(Dermatopathology, Mohs lab & biopsy results at Advanced Dermatologic Surgery)


  • What does “on-site laboratory” mean?

    We process and prepare skin biopsy tissue here in our clinic. For many procedures—especially Mohs surgery—slides are created and evaluated on the same day, in the same facility, so care moves faster and with tighter quality control.

  • How does an on-site lab benefit me?

    • Faster answers: No shipping delays; fewer handoffs
    • Higher quality: Close collaboration between your surgeon and the lab team
    • Convenience: Fewer return visits or phone-tag for results
    • Safety: Chain-of-custody stays under one roof

  • Who reviews my Mohs surgery tissue?

    Your slides are reviewed by Dr. Hocker, a board-certified dermatologist, dermapathologist, and Mohs Surgeon, with dermatopathology support as needed. When a second opinion or special testing is appropriate, we coordinate that for you.

  • What’s the difference between Mohs tissue and a standard biopsy?

    • Mohs surgery: Tissue is processed immediately using frozen sections; your surgeon examines the margins while you wait and continues only if cancer cells remain.
    • Standard biopsy (shave, punch, excision): Tissue is fixed, processed, and examined; results are communicated to you once the report is finalized.

  • How long do biopsy results take?

    Most routine dermatology biopsies return in 3–7 business days. More complex cases that need special stains, immunohistochemistry, or an outside consult can take longer. We’ll keep you updated.

  • Will I get a call even if everything is benign?

    Yes. We contact patients with all results—benign, atypical, or malignant—and document the plan (no treatment, medical treatment, or further surgery).

  • Can I receive a copy of my pathology report?

    Absolutely. Ask at checkout or call us once results are ready. We can also send the report to your primary care provider or referring physician at your request.

  • What if special tests are needed?

    Occasionally, stains or consults with a reference dermatopathology lab provide additional clarity. We arrange that for you; it may add a few days to turnaround and could appear as a separate lab charge depending on your insurance.

  • Is the laboratory certified?

    Our lab operations follow federal and state quality standards (e.g., CLIA) with routine quality-assurance checks, equipment maintenance, and proficiency testing.

  • How accurate are results?

    We use standardized processing, dual identifiers on every specimen, and closed-loop verification between the surgical and lab teams. When appropriate, we obtain second-reader reviews to enhance diagnostic confidence.

  • How will I be notified of results?

    We’ll call you (and/or use your preferred secure method) with clear next steps. If we miss you, we continue outreach and invite you to call the office anytime for an update.

  • Will I receive separate bills?

    You may see separate charges for:

    • The procedure (biopsy or surgery)
    • Pathology (the lab’s preparation/processing)
    • Professional interpretation (the clinician/dermatopathology reading) Coverage varies by plan; our team can help you understand expected benefits.

  • Do I need to stop blood thinners before a biopsy?

    Do not stop anticoagulants unless your prescribing clinician instructs you to. We safely perform most skin procedures while you continue these medications.

  • How should I care for the biopsy site?

    You’ll receive written instructions. In general: keep the area clean, apply a thin layer of ointment if directed, and change the dressing as instructed. Call us for increasing pain, spreading redness, drainage, fever, or bleeding that doesn’t stop with firm pressure for 20 minutes.

  • Can you process tissue taken at another office?

    We typically process specimens obtained in our clinic to maintain safety and documentation. If another clinician collected your biopsy, we can coordinate transfer of slides/blocks or reports—just let us know.

  • Is my information private?

    Yes. All specimens and reports are handled under HIPAA privacy rules with secure labeling, storage, and communication practices.

  • What if I want a second opinion?

    We’re happy to facilitate an independent review or send slides to a trusted dermatopathology partner. This does not delay urgent care—we proceed with the safest plan while consultation is pending when necessary.

  • How do I ask questions about my results?

    Call the office and reference your full name and biopsy date. We’ll connect you with a clinician who can review findings, explain terminology, and discuss treatment options.
