Centegra Hospital Huntley Laboratory Passes Initial CAP Inspection

It is with great pleasure that we announce the successful completion of the Laboratory CAP (College of American Pathologist) inspection at Centegra Hospital Huntley.  We were surveyed Monday May 1, 2017 by 8 Inspectors from various hospitals in the Midwest as well as three College of American Pathologist inspectors.

Our Laboratory successfully met the Laboratory Accreditation Program standards in all areas.  Some corrections or additions of procedures and/or policies are required and will be fulfilled within the next 30 days.  This Accreditation also meets requirements for the Joint Commission and CMS.

The surveyors were very impressed with the quality of the laboratory and the helpfulness of the leaders and the staff.  Their comments were that the laboratory provided high quality care to our patients and was very well organized.  The inspectors stated that this was the best initial inspection they participated in.

The positive outcome of the survey is directly attributed to the daily dedication to quality demonstrated by the Associates of the laboratory.  The Laboratory Leadership and Associates are congratulated on this success!

Helicobacter Pylori Antibody Tests Discontinued

Effective June 6, 2016, all Helicobacter pylori antibody tests will be non-orderable. The tests that are still available are the Helicobacter pylori Breath Test, Helicobacter pylori Fecal Antigen and urease on tissue biopsy.

These changes support the current diagnostic guidelines recommended by the American Collect of Gastroenterology (ACG) and the American Gastroenterology Association (AGA). Antibody tests cannot distinguish between active and past infection with adequate sensitivity and specificity. Despite older literature suggesting that IgG serology can be used as a test of cure 18 months, this has shown to be inaccurate. Both the urea breath test and stool antigen test are FDA cleared for use as tests to diagnose infection and to confirm eradication

If you have any questions or concerns, please contact a pathologist at 759-4806.

Duplicate Labs

Providers will receive a Duplicate Order message when they order certain labs that have already been ordered within a specific period of time under the same visit ID.

The duplicate message does not appear if the test is ordered under a different visit. For example, if a patient has a Hepatitis Panel test done today and comes in again after getting discharged within 2 months, a duplicate message will not show up if a Hepatitis Panel is ordered on that next visit.

The list below displays the test and the frequency timeframe for the Duplicate notification to occur.

Duplicate Labs

If a caregiver ordered HGBA1C on 5/6/14 and if the same lab is ordered within 30 days under the same visit, a “Duplicate Interaction Found” message window is displayed.

Duplicate Labs1

Because HGBA1C was already ordered within a 30 day period, the message below appeared. The caregiver has the option of Overriding or Correcting the order. The Caregiver can also Cancel the order by clicking “Correct Order.”

Duplicate Labs2

By clicking “Correct Order”, the original order will show up. The caregiver then can edit the date for the order and submit it, or “Cancel Order”.

Duplicate Labs3

The screen below will appear when “Override” is selected. The caregiver should type in the reason for Override and click “Save”. Clicking “Save” will submit the order.
