How long has MicroGenDX been serving patients?
MicroGenDX, formerly known as Pathogenius, has been in operation since 2008. In 2017, the company was purchased by Rick Martin and rebranded as MicroGen Diagnostics Laboratory.
What are the advantages of MicroGenDX's NGS technology?
• Rapid turnaround for PCR lab results, typically within 24 hours of sample receipt
• Detection of resistance genes to aid in better antibiotic stewardship
• NGS technology offers superior specificity in detecting microbes
• Fast results within 3-5 business days
• Simultaneous identification of bacteria, fungi, and antibiotic resistance genes
• Detection of bacteria even in the presence of antibiotics
• Increased sensitivity and simplicity of sample collection
• Cost reduction and avoidance through better antibiotic stewardship
• Enhanced clinical value by reducing identification subjectivity associated with traditional culture methods
• Increased patient satisfaction
Technology
What is PCR?
PCR is a molecular biology technique that amplifies DNA sequences, enabling precise detection of microbial DNA in patient samples. PCR is like a flashlight in a dark room. It can light up some areas, but not the whole room.
What is Next Generation Sequencing (NGS)?
NGS, also known as high-throughput sequencing, allows for the simultaneous sequencing of millions of DNA strands, providing comprehensive insights into the microbes that make up your sample. If PCR is a flashlight, NGS is like flipping on the switch to the whole room.
How do I select the appropriate test?
Choose the test that best matches the area of the body that you believe to be the center of the infection. More details as to what infections each test works best for are available on the product page.
Why does MicroGenDX provide two separate lab reports?
• Rapid PCR Level I delivers microbial detection and resistance genes within 24 hours, while NGS Level II provides comprehensive results within 3-5 business days, ensuring thorough analysis.
• Having two levels allows for fast reporting for some commonly known pathogens which allows for quick action on well-known pathogens without sacrificing the searching power of NGS.
What is the sensitivity and specificity of NGS testing?
Sensitivity and specificity are determined through rigorous validation protocols, ensuring accurate detection of microbial targets.
What considerations are important for diagnosing urinary tract infections?
UTIs may involve multiple organisms, and NGS technology can detect them simultaneously, offering comprehensive insights into the infection.
How do you determine if bacteria species are “viable”?
Viable bacteria can be distinguished by the presence of live DNA, which remains stable for weeks after collection.
Testing
Will medication affect test results?
Some medications, like anti-herpes drugs, may impact test sensitivity by reducing viral shedding. It's essential to follow any instructions provided by your healthcare provider regarding medication usage before testing.
Does MicroGenDX test for parasites and sexually transmitted diseases?
Yes, MicroGenDX offers testing for parasites through the GI Test Service and a range of sexually transmitted diseases through various tests.
Lab Report
How can I access my lab reports?
Lab reports can be accessed through the MicroGenDX patient lab portal.
How do I interpret PCR and NGS lab reports?
Link to understanding your lab results page.
What do the “antimicrobials for consideration” section mean?
We offer suggestions for antibiotics that could help treat each type of bacteria we find. These suggestions come from trusted sources like the Sanford Guide and Johns Hopkins Guides. It's also important for your doctor to check your local antibiogram, which tracks which antibiotics work best against germs in your area.
Why do some species appear in Level II but not Level I reports?
NGS has the ability to detect bacteria even if they are mutated beyond the detection capabilities of PCR. This is because PCR detects organisms using specific gene primers, if those primers are mutated, the organism will not be detected. NGS uses broader and different primers then PCR.
Specimen Collection
What specimens are acceptable for testing?
MicroGenDX accepts various samples, including urine, blood, fluid, tissue, and fecal matter, with specific guidelines provided for each test service.
Is urine suitable for bacterial vaginosis and candidiasis testing?
Yes, urine is an acceptable specimen for these tests.
How should I collect samples for testing?
Detailed instructions for sample collection are provided with each test kit to ensure accuracy and prevent contamination.
Negative or Inconclusive Lab Report
Why did I receive a negative report?
Negative results may occur due to various factors, including sample quality and the presence of biocides or host DNA. However, they may also be indicative of a lack of infection (depending on the sample collection site). Please consult your physician before interpreting such results.
Ordering
How can I order a test as a patient?
Patients can order test kits online through this website (with telehealth support) or by calling (855) 208-0019.
What is the cost of testing?
Test prices vary, with most qPCR+NGS tests priced at $249 for self-pay patients within the United States.
How can I obtain my results?
Results can be accessed through the patient portal or by calling the MicroGenDX office at (855) 208-0019.
How can I send a sample to the lab?
Test kits include all necessary collection materials and a prepaid FedEx label for convenient sample submission.
How long should I discontinue antibiotics before testing?
Ideally, antibiotics should be discontinued 48 hours prior to testing, unless otherwise instructed by a healthcare provider. Always check with your health care provider before discontinuing any medications.
Will other medications (such as pain medication) affect the sample?
While some medications may impact test results, pain medication typically does not affect samples.
Why is a doctor's authorization required for testing?
In the U.S. medical system, physician authorization is necessary for legal compliance and accurate interpretation of test results.
Is proper sample collection important?
Yes, following illustrated instructions for sample collection ensures accurate test results. Failing to collect samples according to instructions could decrease the quality of results due to contamination or even lead to a negative (no organisms found) test result.
