Helicobacter pylori Diagnosis – Serologic Testing is no Longer Recommended

Overview

Clinical guidelines no longer recommend serologic testing as a method for the diagnosis of H. pylori infection. Rather than IgG serology testing, other non-invasive testing methods such as H. pylori stool antigen and urea breath tests may be used to both diagnose and monitor response to therapy for H. pylori infection. In anticipation of an increase in stool antigen testing, currently a reference lab send-out test, Spectrum Health Regional Laboratory (SHRL) will be implementing this test as of October 29, 2018. By offering this test in-house, results will typically be available one day faster than present state. Continue Reading

Spectrum Health Regional Laboratory Discontinues Influenza Rapid Antigen Testing

There has been a minor change to the influenza testing methods performed by the Spectrum Health Regional Laboratory (SHRL) to improve the accuracy and timeliness of patient results, while simplifying the ordering process for providers. In past years during respiratory illness season, the lab performed influenza rapid antigen testing due to its low cost and rapid turnaround time, with negative specimens reflexed to PCR for confirmatory testing. Approximately 85% of specimens tested by a rapid antigen method typically reflexed, with those patients charged for performing both tests. Continue Reading

Test Name Change: Throat Culture Comprehensive

On June 27th, the name of the current order “Respiratory (non-sputum) Culture without Gram stain” will change to “Throat Culture Comprehensive.” All other specimen collection details and culture workup will remain the same. Given the fact that there are currently several similarly named tests, this change is being made to reduce confusion regarding test selection and to clarify acceptable specimen types.

Utility of specific IgE (sIgE) testing to foods and food allergen components

The diagnostic evaluation of allergic disease occurs in the context of a patient’s complete clinical presentation. Important factors include, age, clinical signs and symptoms, relevant allergen exposures, and the performance characteristics (sensitivity, specificity, and predictive values) of the allergy tests themselves. Allergy tests yield information about sensitization to allergens, which is not always equivalent to allergic hypersensitivity (i.e., sensitivity); thus, interpretation in the context of clinical history is essential for accurate diagnosis.
