Frequently Asked Questions

How are the results delivered? 2013-10-07T13:28:09+00:00

Normally we deliver the pathology results by secure email. By special request, we can also fax or mail the results.

How do we get trained on the procedure? 2013-10-07T13:24:42+00:00

Please contact the company and we will send a Clinical Specialist to your facility to train the Doctor and staff on the procedure. While the WATS procedure is not difficult or complicated to perform, there are a few critical steps that must be learned and adhered to.

How do we get started? 2013-10-07T13:22:53+00:00

Please contact our corporate office at 1-866-363-6239 and we will be glad to have one of our sales representatives contact you directly.

Does it matter if I take a forceps biopsy or WATS3D biopsy first? 2014-01-07T19:39:46+00:00

This is the subject of current investigation. We generally recommend that the WATS biopsy be taken first so as to minimize the effect on the WATS sample of bleeding induced by a prior forceps biopsy. If the WATS biopsy is performed after the forceps biopsy, then bleeding caused by forceps biopsy should first be cleared.

What are the steps to ensure the best WATS tissue samples? 2013-10-11T15:05:50+00:00

Apply sufficient pressure against the tissue to obtain micro bleeding and then insure that the fixative is applied within 5 seconds of preparing the smear.

How much does the kit cost? 2013-11-08T14:30:08+00:00

Test kits are provided to the physician free of charge. Al materials needed to collect the tissue sample are enclosed in the kit. Once the biopsy is taken, specimens are placed back inside the kit for pre-paid overnight return shipment to our lab via UPS.

How can I order kits? 2013-11-08T14:26:59+00:00

Please contact your CDx representative to order or reorder kits.  If you don’t currently have a rep, please contact our corporate office at 1-866-363-6239 and we will be glad to help you.

How quick is the results turnaround? 2013-10-07T13:19:23+00:00

Typically, the results are delivered within 4 to 5 days of receipt of the sample in our lab.

Do we have to send the specimen to your lab? 2014-01-07T19:41:47+00:00

Yes. The WATS3D biopsy instrument yields a wide-area disaggregated tissue specimen which is transepithelial, capturing the entire thickness of the esophageal epithelium. This enriched specimen is unique in pathology and unlike traditional histology is uncut to preserve all cellular information from all focal planes. To optimize sensitivity the WATS specimen requires CDx Diagnostics’ specialized three dimensional computer assisted analysis to assist the CDx GI specialty pathologists that review each case.

Can I use the brush for anything else? 2013-10-11T15:01:49+00:00


Do you have GI pathologists? 2013-10-11T15:01:14+00:00

All CDx Diagnostics pathologists specialize in WATS3D analysis of GI specimens

Is there an internal review from a second pathologist if dysplasia is detected? 2013-10-11T15:14:48+00:00


What are indications for the WATS3D biopsy? 2014-01-07T19:40:55+00:00

You can perform the WATS3D biopsy procedure on any patient where the goal is to rule out Esophageal Disease. Most frequently, our physicians use the WATS Biopsy when screening for Barrett’s Esophagus or when they are looking for Dysplasia in known Barrett’s patients.

How long does it take to perform the WATS3D biopsy? 2014-01-07T19:41:16+00:00

In most cases the WATS3D biopsy can be performed in about a minute.

How is the 3D analysis done? 2016-12-15T15:52:37+00:00

The specimen is optically imaged in 50, 1 micron slices which are then integrated together to form a three dimensional image.

Does the physician continue to take a biopsy with forceps? 2013-10-11T15:05:03+00:00

WATS is not intended to be a substitute for targeted forceps biopsy of suspicious areas.
