Where Is NP Screen® Testing Available

Currently the NP Screen® assay has been released on a limited basis. NP Screen® assay may only be performed by a qualified clinician. For availability of the test in your area click on Contact Us at the bottom of this page.

How Is The Test Sample For The NP Screen® Test Collected And What Should I Expect
The collection procedure is similar to the common throat swabbing, but in this case the swab is designed to constrain collection of specimen to the post-nasal space where NPC first develops. The procedure is simple, painless without the use or need for any anesthetic and is quickly completed in a few seconds.

Can NP Screen® Be Used To Diagnose NPC
No. Only a confirmatory procedure such as biopsy evaluation by a pathologist may be used to diagnose NPC. NP Screen® is only a screen which is used to assess a patient's need for a confirmatory procedure such as biopsy.

Can NP Screen® Predict Future Occurrence Of NPC
No. NP Screen® can only assess a patient's current risk for NPC and can not predict future abnormalities.

Is NP Screen® A Cure For NPC
No. NPC may only be cured by one of or a combination of radiation therapy, chemotherapy or surgery.

How Rapidly Does NPC Develop
How rapidly NPC develops is not completely understood. Doctors experienced with NPC believe it takes six to twelve months for newly formed abnormalities to become clinically overt.

What Does A Negative NP Screen® Result Mean
Based on clinical trials, a negative result indicates that with greater than 99% probability the patient will not diagnose for NPC.

What Does A Positive NP Screen® Result Mean
Based on clinical trials, a positive result is consistant with a diagnosis for NPC.

My NP Screen® Result Was Negative But My Test Result Showed Some abnormalities. Why?
Healthy, cancer free patients may report no to very low, transient, abnormality levels, this is normal.

How Often Should I Take The NP Screen® Test
Similar to tests for cervical cancer, breast cancer and prostrate cancer, NP Screen® should be taken regularly, at least annually. In patients with a predisposition for NPC, semi-annual testing may be considered because treatment outcome is dependant on early detection.

What Should I expect After the Test
Within two to three weeks after the specimen collection procedure the laboratory results will be reported to the physician who performed the procedure. The physician's office will contact you and advise the results and the appropriate follow up actions if any are required.
