What is the principle of Cepheid GeneXpert machine?
Principle of the Procedure This assay can be performed on Cepheid GeneXpert® Instrument Systems. GeneXpert Instrument Systems automate and integrate sample purification, nucleic acid amplification, and detection of the target sequence using real- time reverse transcriptase PCR (RT-PCR) and real-time PCR assays.
What is GeneXpert device?
How it works ———— The Gene Xpert is a machine that can detect *mycobacterium tuberculosis* in a sample of sputum. A person suspected of having TB needs to give a sputum sample, which the health care worker than places in a small tube.
What is CT NG method?
INTENDED USE. The AMPLICOR CT/NG Test for Chlamydia trachomatis is a qualitative in vitro test for the detection of C. trachomatis plasmid DNA in urine from males and females, in endocervical swab specimens, and in male urethral swab specimens as evidence of symptomatic or asymptomatic infection with C. trachomatis.
What is CT ng RNA PCR?
The Abbott RealTime CT/NG assay is an in vitro polymerase chain reaction (PCR) assay for the direct, qualitative detection of Chlamydia trachomatis and Neisseria gonorrhoeae.
What type of test is Cepheid?
With 20 FDA-cleared tests (including moderate complexity and CLIA waived tests), Cepheid is the ideal diagnostic RT-PCR partner for improved clinical decision making and patient care.
What is a Cepheid test?
Cepheid has developed an automated molecular test for the qualitative detection of SARS-CoV-2, the virus that causes COVID-19. The test leverages the design principles of our current Xpert® Xpress Flu/RSV cartridge technology, in which multiple regions of the viral genome are targeted.
How GeneXpert test is done?
A sputum sample is collected from the patient with suspected TB. The sputum is mixed with the reagent that is provided with the assay, and a cartridge containing this mixture is placed in the GeneXpert machine. All processing from this point on is fully automated.
Is Guanaria curable?
Yes, the right treatment can cure gonorrhea. It is important that you take all of the medicine your healthcare provider gives you to cure your infection. Do not share medicine for gonorrhea with anyone. Although medicine will stop the infection, it will not undo any permanent damage caused by the disease.
What does CTNG mean?
Chlamydia trachomatis and Neisseria gonorrhoeae (CTNG) by Transcription-Mediated Amplification (TMA) with Reflex to CT/NG Confirmation. Sexually Transmitted Infections.
What does not detected mean on STD test?
Your STD test results may indicate “reactive,” “not-detected,” “non-reactive” or a reference range. Not detected and non-reactive mean the STD was not detected in your system. The reference range indicates whether the STD value is high enough to be considered positive; if not, it returns negative.
What causes drop infection in males?
Gonorrhea can be passed even if the penis doesn’t go all the way in the vagina or anus. The main ways people get gonorrhea are from having vaginal sex, anal sex, or oral sex. You can also get gonorrhea by touching your eye if you have infected fluids on your hand.
Can you get chlamydia from kissing?
Chlamydia isn’t spread through casual contact, so you CAN’T get chlamydia from sharing food or drinks, kissing, hugging, holding hands, coughing, sneezing, or sitting on the toilet. Using condoms and/or dental dams every time you have sex is the best way to help prevent chlamydia.
Can I test negative for STD and still have it?
It is possible to get a negative test result and still have an STD. Given the potential impact of some STDs—from genital warts to fertility issues to cancer and more—it may seem unlikely that you could have one and not know it. But very often, that’s the case.
What kind of testing is Cepheid?
Tests. With 20 FDA-cleared tests (including moderate complexity and CLIA waived tests), Cepheid is the ideal diagnostic RT-PCR partner for improved clinical decision making and patient care.
How accurate is the Cepheid GeneXpert CT/ng assay for gonorrhea?
In summary, the Cepheid GeneXpert CT/NG assay performance was highly accurate and reproducible and can be recommended for detecting both chlamydia and gonorrhea in cervical, vaginal, and urine specimens from women and in urine specimens from men.

How accurate is the Xpert CT/ng assay?
Relative to the PIS, the Xpert CT/NG assay demonstrated a sensitivity and specificity for C. trachomatisfor patient-collected vaginal swabs of 98.7% and 99.4%, respectively (Table 2). Sensitivity and specificity estimates for C. trachomatisfor endocervical swabs were 97.4% and 99.6%, respectively.
How are Xpert CT/ng performance characteristics compared to ASIS?
Performance characteristics of Xpert CT/NG were determined in a multi-site prospective investigational study at 9 US institutio ns by comparing Xpert CT/NG to the anatomic site infected st atus (ASIS) algorithm based on combined results from two NAAT tests, with a tiebreaker NAAT test if applicable.
