Pcr Nasal Swab
Pertussis was foun: It means that they found evidence that the bacteria that causes whooping cough was present in the nasal passages. This could mean you are a carrier of the disease (could infect others) or if you are having symptoms or repeated, serious cough, then you likely got infected by the pertussis bacteria and have whooping cough. ...Read more
Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more
I tested positive for Uraeplasma Parvum PCR. My husband has had an affair and I thus contracted this from him. He claims this can be transferred by means of coughing or sneezing in someone's eye or nose. Can you confirm that this is an STD?
Considered STD: The organism is considered a STD but it can also be transferred through a cough or a sneeze. Because of your circumstances you need to discuss this further with your doctor. Since the pcr was positive, I believe you have an STD and follow your doctors recommendations. Good luck ...Read more
Germs you carry: The nasal membranes are a luxurious environment for germs to grow and end up on your fingers where they are spread to the environment. Screening nasal swabs is one way to find a source for staph or other germ that may not infect the carrier but might cause problems with the rest of their family. ...Read more

Rapid screening test: Dfa--direct fluorescent antibody test--a rapid diagnostic test done in the lab that takes 1-2 days to screen for pertussis (whooping cough). While much faster than a culture, this test is not as reliable. A nasal swab is inserted gently into the nostrils toward the throat (posterior nasopharynx). Then fluorescently labeled antibodies are exposed to the sample looking for pertussis antigens/markers. ...Read more
If mrsa swab of infected area is negative after infection, is mrsa gone? Does an infection mean I am a carrier? Do I need to follow up w/ nasal swab?
MRSA carriage: There is s lot of media attention and literature on MRSA in recent yrs. Resulting in some confusion. If you had MRSA diagnosed before, thud chances are that you are colonized with it. Thx good news is that you can decrease colonization with proper monitoring and treatment as indicated. ...Read more
Nothing special: The presence of staph on a nasal swab means only that you are carrying a strain in the lush mucoid environment where it can thrive. It doesn't do well on the dry skin surface for long periods of time. With it in your nose you could spread it to bug bits by scratching with contaminated fingers, or to door handles or other objects. Since most have no symptoms, nasal carriage allows it to spread. ...Read more
If a person has a nasal swab done & it cultures positive for "staph lugdunenis" but has no apparent signs of infection/illness what should be done?
Nasal Swab: The three most common bacterial pathogens causing upper respiratory infection in adults are Moraxella catarrhalis, Streptococcus pneumoniae, and Haemophilus influenzae. A nasal swab is performed to culture and see what pathogen is causing problems. Haemophilus is a normal colonizer, but when isolated from sputum during infection it can indicate colonization has morphed to pathogenicity. ...Read more
Swollen turbinates for last 6 months. Dx vasomotor Rhinitis. Positive nasal swab for Coag Negative staph. Could this be cause of Vasomotor Rhinitis?
Definitely not: A culture like that is essentially useless. Staph CN organisms in this setting are 'just along for the ride' and have nothing to do with your sinus disease. That might have been different if a true pathogen was found (like Strep) but I'm pretty sure this is just what we call 'normal flora'. The sinuses are not a sterile place, so there are ordinary bacteria there. I would seek more about ALLERGY. ...Read more
I was recently diagnosed with mrsa via groin swab. Took bactrim, (sulfamethoxazole and trimethoprim) no visible rash. Do I need to be retested and have nasal swab? Am I a carrier now?
CONFUSING QUESTION: It is not clear why you had a swab done in your groin. If you had pustules or weepy lesions, mrsa is a reasonable cause. Once treated, you are unlikely to be a chronic carrier of the same germ. Retesting is not routine. Mrsa is so common now you could easily acquire a new strain within days or weeks. ...Read more
Swollen nasal passages for three months. Nasal swab found large amount of coagulase negative staph. Doctor wants me to take keflex. I was on keflex for 5 years low dose to treat e-coli UTI which is now resistant to keflex. Wont staph be resistant to?
No: A person doesn't get resistent to an antibiotic, but a germ can. If you have not been on keflex in the past months it would likely kill off some of the germs on your body. However; I find coag negative staph to be a normal skin contaminant and not worthy of any treatment. Use of a simple OTC nasal steroid spray like rhinocort would help with most causes of nasal membrane swelling. ...Read more

Virus likely present: Pcr (polymerase chain reaction) is a biochemical lab procedure sometimes used to test for a virus you might have. If the test is right, the virus tested really is there : (the test can however, be a false positive (meaning it was positive, but the virus is not really there). Results vary depending on a number of factors. Talk with your pcp about the meaning of your result and what to do next. ...Read more
Molecular testing: Pcr = polymerase chain reaction. This is a very sensitive type of molecular lab testing in which tiny pieces of genetic material are amplified over and over again under controlled conditions to assess for the presence or absence of specific genetic material and/or to characterized that material. Pcr can be used for genetic testing, diagnosis of infections, cancer testing, and other things. ...Read more

Nucleic acid Test: Hiv is a RNA virus. Nucleic acid testing (nat) is done to (1) detect virus for an early diagnosis after potential exposure; (2) donated blood to detect infection, (3) to measure the viral load in someone undergoing treatment for hiv. Nat may be negative up to two weeks or so after acquiring infection. It is the most accurate of the tests for hiv. ...Read more
