• One day results (determined by sample receipt) • Cost reduction and avoidance • Reduced antibiotic utilization • Increased patient satisfaction • Greater clinical value - by reducing the subjectivity of identification associated with conventional culture technology
Polymerase chain reaction (PCR) is a molecular biology technique that amplifies a DNA base pair sequence up to several orders of magnitude (billions and trillions of copies).
• One day results (determined by sample receipt) • Simultaneous identification of bacteria, viruses, parasites, Candida and antibiotic resistance • Detection of bacteria in the presence of antibiotics • Increased sensitivity and specificity • Simplicity of single sample collection
Many pathogens have overlapping symptoms, making it a challenge to determine the causative organism based only on patient presentation. The true benefit of
Diatherix tests for resistance genes that are specific to staphylococcus. When resistance genes are found in clinical specimens, the particular class of antibiotics affected by the detected resistance gene should be avoided when applying antibiotic coverage.
No. Diatherix does molecular testing, not microbiological testing.

Diagnostic tests such as
Multiplex molecular technology (
Although quantitation is important for certain infections such as determining viral load in Hepatitis C and HIV to adjust antiviral dosing, quantitation in bacterial infections can vary with the particular infection and the patient involved. In effect, the number of organisms infecting one patient may not be the same with another. Establishing some arbitrary threshold to determine whether someone is infected would not be accurate or practical.
Both sensitivity (or the limit of detection – LoD) and specificity of
There are multiple reasons for a negative result. First, not all potential pathogens are tested on our panels. Our panels are designed to capture the most common causes of infection at a particular anatomic site. The value of a negative result provides the information that the most common pathogens for that particular site could be excluded. Second, infections in sterile sites such as the bloodstream or synovial fluid have a very low number of organisms, and could be below the limit of detection of our test for a particular target. Lastly, the collection of the specimen is key in obtaining an accurate result. For example, if a lower respiratory infection is suspected, then the specimen source should be from lower airway secretions instead of a nasopharyngeal (NP) swab.
Antibiotic resistance gene targets detected on the Diatherix panel are best interpreted when staphylococci or enterococci are also detected on the panel. Although other organisms may have the genes that we detect, most of the Gram negative bacteria that may be detected in our panels can have other resistance genes that are not included in our test menu at this time. Our technology reliably and rapidly identifies microorganisms. The selection of an appropriate antibiotic that can be used to treat a clinically apparent infection is based upon standard ‘bug-drug’ combinations as outlined by references such as the Sanford Guide, or an antibiogram from a local hospital.
The upper respiratory tract is heavily colonized with a variety of bacteria that are part of our natural flora; now being referred to as our microbiota. It is now recognized that several bacteria and viruses that cause infections such as otitis media, pharyngitis, and sinusitis can be found in both symptomatic and asymptomatic patients. Making a diagnosis of infection is dependent upon getting a comprehensive accounting of the organisms present, associating them with compatible clinical signs, and companion diagnostics. The identification of multiple detections may reflect a more problematic course of infection for a patient with significant symptoms.
While the exact significance of a given combination of detected pathogens is hard to determine, we do know that there is often synergy between pathogens. This can be between viruses and viruses, viruses with bacteria, and bacteria with bacteria. For example, at least 90% of all pneumonia cases begin with an antecedent viral illness. The interaction between multiple organisms (both viruses and bacteria) is the rule rather than the exception. As with all diagnostic reports, the provider should consider the results as indication of the presence of the pathogen(s), rather than proof of active infection. Considering the reported organism(s) with respect to the clinical presentation to arrive at the diagnosis.
A significant number of patients have, as a part of their microbiota, organisms that can cause significant disease when found in a sterile site such as the blood or spinal fluid. One such organism is Neisseria meningiditis. It is now recognized that between 10 to 20 percent of children may harbor this organism as a part of their microbiota intermittently or continually and remain asymptomatic. Detecting the presence of ‘would-be pathogens’ is important in that the patient can be a reservoir of infection for immune-compromised family members or friends. In addition, the patient’s immune competence is not always a constant and knowing that a potentially problematic organism is a part of the patient’s microflora can be important for early recognition of significant disease downstream.
Recurrent or chronic UTIs are sometimes the result of more than just a single infectious organism. Urine culture is biased towards a single infectious organism based on CFU (colony-forming unit) count, possibly leading to inappropriate therapy. Some problematic organisms are not readily grown in culture which may lead to incorrect treatment or non-treatment. The advantage of
The patient’s clinical symptoms and presentation must dictate the type of specimen and collection technique used. Although urine is an acceptable method of collecting STD specimens, the selection of a specimen type should be considered based on the patient symptoms and clinical presentation. Please refer to the recommended collection techniques for STD specimen collection published by Diatherix.
Current research suggests that Toxin B, and not Toxin A is required for virulence. Given the evidence for the role of tcdB (not tcdA) in the pathophysiology of pseudomembranous colitis, we have excluded the Toxin A target from the panel. Some labs have chosen to combine Toxin A/B, and do not differentiate between the two.
Bordetella parapertussis is similar to B. pertussis and causes a pertussis-like illness. However, B. parapertussis does not produce the pertussis toxin and therefore the infections are typically milder and often asymptomatic. The CDC estimate is that B. parapertussis produces 1%-35% of infections that are ‘pertussis-like’. Given the symptoms and prevalence, our focus is on B. pertussis.
Laminar flow immunoassays that are in place in most hospitals and physician offices detect the hemagglutinin (H) only and not only lack sensitivity but, also, lack the ability to determine the specific neuraminidase (N) component. In that regard, we are currently the only laboratory in the country that can accurately determine both the hemagglutinin and the neuraminidase of the H1N1 strain.
MRSA often colonizes the external nares, the axilla, and the perineum of a growing number of people. When the organism produces disease, it is often mechanically introduced into healthy tissue by self-inoculation (scratching mosquito bites, contact with cuts or scratches, etc.), or during surgical procedures when patients are not effectively decolonized before the surgery is performed. Whether a patient has MRSA disease and is in need of treatment is a clinical decision and is based upon whether the specimen is properly collected and if the patient is symptomatic.
Anti-herpes medications disrupt the process by which the virus makes copies of itself and spreads to new cells. The antiviral works by inhibiting an enzyme that the virus has, but human cells do not, and therefore interrupts the virus’ ability to synthesize its DNA. By reducing the replication of the Herpes virus, the number of virus particles shed by the host is reduced and tests (even molecular assays) may not always be able to detect viral shedding.
HKU1, 229E, OC43 and NL63
Yes. The Gastrointestinal Panel includes Giardia lamblia and Cryptosporidium parvum.
Recommendations from both the CDC and the IDSA conclude that toxin B is the primary toxin responsible for disease produced by Clostridium difficile.
With the understanding that pharyngitis is most often caused by viruses, the Pharyngitis Panel includes Group A Strep as well as other organisms that either cause or contribute to the severity of symptoms.
Atypical Pneumonia Panel
Yes, under the appropriate clinical circumstances.
Tissue can be accepted as a specimen source but it is recommended that the tissue be pulverized/ground up before placing in collection tube.
No, urine can only be tested for an STD in the orange cap tube.
Add approximately 1mls of urine to the 1ml of fluid already in tube.
