Intended Use
hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test is a rapid, convenient, and non-offensive qualitative method for detecting occult blood in the stool. It is intended for professional use as an aid in the diagnosis of asymptomatic gastrointestinal conditions that may manifest themselves by the presence of occult blood in the stool. This test is recommended for use in routine hospital testing, mass screening programs for colorectal cancer, and in testing of postoperative patients and newborn infants.
Device Description
hema-screen ER XCEL™ in its original concept as slides and tape was designed to offer the hospital, mass screening programs and clinical laboratories a convenient rapid method for handling fecal specimens in testing for occult blood. hema-screen ER XCEL™ is especially useful for mass screening programs as its enhanced readability feature facilitates the technicians' ability to make a determination. hema-screen ER XCEL™ eliminates the mess and odors associated with the collection and transport of fecal specimens. Slides can be prepared at the patient's bedside and placed in a sealed envelope or by the patient at home and mailed to the hospital or laboratory in an inoffensive manner for development and evaluation. hema-screen ER XCEL™ single slides are convenient for use when single stool specimens are to be tested. A single test is indicated when blood loss in the gastrointestinal tract is strongly suspected, for example, in persons with symptoms of ulcers, anemia, black stools or postoperative patients. hema-screen ER XCEL™ Enhanced Readability Patient Packs are to be utilized so the patient can serially collect specimens at home over the course of three bowel movements. Patients should be instructed to follow the directions exactly, as the potential for false positive results exists due to improper diet, blood on the hands, hemorrhoids or if the test is used during menstrual bleeding. After all three slides are prepared, the slides may be sent back to the hospital laboratory for developing and evaluation. Preparation of three consecutive slides is recommended for screening asymptomatic patients by the American Cancer Society. When stool specimens containing occult blood are applied hema-screen ER XCEL™ test paper, the hemoglobin portion of the occult blood comes in contact with the guaiac. When the hema-screen ER XCEL™ peroxide developing solution is added, a guaiac-peroxidase like reaction occurs. The chemical reaction becomes visible by the appearance of a blue-green color between 30 seconds and 60 seconds if occur blood is present.
More Information

Not Found

No
The description details a chemical reaction-based test for detecting occult blood, with no mention of AI or ML for analysis or interpretation. The "enhanced readability" refers to a feature facilitating human interpretation, not automated analysis.

No.
The device is described as a diagnostic tool ("aid in the diagnosis") for detecting occult blood, not for treating or preventing a disease.

Yes

The device description states its intended use as "an aid in the diagnosis of asymptomatic gastrointestinal conditions that may manifest themselves by the presence of occult blood in the stool." This explicitly identifies it as a diagnostic tool.

No

The device description clearly outlines a physical test kit involving slides, tape, and a developing solution, indicating it is a hardware-based medical device for detecting occult blood in stool.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states it's a method for detecting occult blood in stool, which is a biological specimen. It's used as an aid in the diagnosis of asymptomatic gastrointestinal conditions.
  • Device Description: The description details how the device interacts with the stool specimen (applying it to test paper) and how a chemical reaction occurs to indicate the presence of occult blood. This is a characteristic of in vitro testing.
  • Mechanism of Action: The explanation of the guaiac-peroxidase like reaction occurring when the developing solution is added to the stool specimen on the test paper describes a chemical process performed outside of the body using a biological sample.

Therefore, based on the provided information, the hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test fits the definition of an In Vitro Diagnostic device.

Principles of Test

Slides can be prepared at the patient's bedside and placed in a sealed envelope or by the patient at home and mailed to the hospital or laboratory in an inoffensive manner for development and evaluation.

hema-screen ER XCEL™ Enhanced Readability Patient Packs are to be utilized so the patient can serially collect specimens at home over the course of three bowel movements.

Technological Characteristics:

The fundamental scientific technology of the modified device has not changed. The change is for the addition of an optional patient sampling slide with GRID: the internal guaiac paper has neither been modified nor reformulated; the outer cardboard contains smaller surface area (small circles) to help prevent oversampling and ease of use for the patient.

There is no change in analytical sensitivity of the new device.

The intended use/indication use of the modified device as described in the labeling has not changed.

Name change to hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test. Both patient sampling slide versions (GRID and Non-GRID) are available and optional in hemascreen ER XCEL™ Enhanced Readability Fecal Occult Blood Test.

Design Control Activities Conducted:

A Risk Analysis was used to assess the impact of the modifications on the device and its components, and the results of the analysis.

Based on the Risk Analysis, an identification of the verification and/or validation required, including methods or tests used and acceptance criteria was applied and found to be satisfactory. A Declaration of Conformity statement with design controls is presented.

Conclusion Drawn:

The hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test is as safe and effective as the predicate device, hema-screen TM ER.

The hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test has the same intended use and indications for use and fundamental scientific technology.

The difference between the subject device, hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test and predicate device, hema-screen" ER (addition of an optional GRID design version of the hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test) raises no new issues of safety and effectiveness.

The hema-screen ER XCEL™ Enhanced Readability Fecal Occult Blood Test is substantially equivalent to the predicate device.
