This has increased the sensitivity and specificity of our multi vaginosis panel
What is the removal of gardnerella as a target?
By doing this regarding Strep A, complications such as Rheumatic fever, sepsis, pneumonia, and meningitis may occur.
What is leaving Strep A untreated?
Nasopharyngeal and anterior swabs are approved for this Cepheid product line

What is: One and Done PCR, PCR + Toxin Confirmation, GDH + PCR Confirmation, and GDH + Toxin + PCR Confirmation?
From a sample collection standpoint, Cepheid offers a unique option around this that many sexual assault survivors may find interest in.
What is patient self collection?
The Xpert Xpress Strep A test has been validated with only the following collection devices.
What is the Copan Liquid Amies Elution Swab (ESwab) Collection Kit (Copan 480C or Copan 480CE or Copan 480CFA)
Cepheid addresses potential CoV-2 variants with its array of targets (3). Those gene targets are the N2 gene, E gene, and the RdRP gene. Cepheid did this for this reason.
What is Cepheid's plan for dealing with mutations or variants from CoV-2?
Resistance is now known to be conferred when SA acquires a Staphylococcal cassette chromosome (SCC) mec gene containing either of these two types of mec
What is Mec C and Mec A?
This is slow and inaccurate however, up front costs are much lower than PCR.
What is culture testing?
A customer is excited about upgrading their MRSA from BD Affirm to BD Max. However, clinically they will still have the same problem which is this.
What is false negatives from the inclusion of gardnerella?
The main takeaway of this impact brief detailed a decrease in the length of stay by 21 minutes per patient, as well as an improvement in LWBS scores from 2.4% to 1.2%
What is the Willis Knighton Impact Brief?
No early assay termination (EAT), freezing samples not being recommended, and a recommendation to test sample within 7 days of collection would all be considered this in regards to the 4 Plex test
What are the limitations of 4 Plex?
This MRSA test requires skin or soft tissue at the infection site.
What is the MRSA/SA SSTI assay?
This is the primary measure used by the National Healthcare Safety Network (NHSN) to track healthcare associated infections.
What is the Standard Infection Ratio or SIR

These are Streptococcus groups associated with less than 5% of Pharyngitis. Usually seen in the adolescent.
What is Strep C and Strep G?
These guidelines say the following:
Clinicians should test all patients presenting with acute onset respiratory symptoms.
Clinicians should use a rapid molecular assay (ie., nucleic acid amplification tests) over rapid influenza diagnostic tests (RIDT).
Multi-plex RT-PCR recommended
What are the ISDA guidelines for respiratory testing?
48+ hours of unknown MRSA colonization status is the result of this.
What is the result of a culture MRSA test?
This is what the IDSA, ACG, and SHEA guidelines state regarding appropriate samples for Cdiff testing.
