Can A Herpes Culture Test Be Wrong
Not exactly: It is not so much the blood test is wrong, as it might be too early after infection to show up. Culture only positive if "catches" the organism to grow. There are a couple of types of herpes (hsv1/hsv2) as well. Usual to repeat blood work after 3-6 months if equivocal results. ...Read more
A herpes culture is a test performed in a microbiology or virology lab, where they use a swab from a suspicious area and try to "grow out" the herpes virus. This kind of test is notoriously inacurate- and a negative viral culture should not be taken as proof that you don't have the herpes virus. It should be followed up with blood testing to confirm that you have not ...Read more
Depends on timing: False negatives can occur, especially if the ulcer is cultured too late, after healing has already begun. False negatives are less likely to occur when the culture is taken from an intact vessicle (blister) that has been opened for the purpose of the culture, or from a very fresh ulcer. ...Read more
How likely is it for a herpes culture test to be a false negative if I went within the first few days of my outbreak?
10%: The test is 90% accurate in this scenario you described. ...Read more
Herpes culture: A positive culture means that the virus was present and actually grew and multiplied in the lab. The only way it would be wrong is if the made some kind of mistake with labeling your specimen and mixing it up with somebody else. That would be very very very rare for a culture. ...Read more
Unlikely: A false positive result would be extremely unusual. It would require either laboratory contamination or a clerical or technician error in which the result was reported for the wrong patient. I trust herpes culture results. ...Read more
Likely OK.: I don't know what your history is but if you had/have a herpes infection, you likely would have noticed skin lesions that could be irritating at some point in time. Many times there can be no symptoms but if you have this there would be some kind of outbreak at some point in time. The tests include tzank prep. Of scrapings that show giant cells, cultures are pos. In 48-96 h, elisa+pcr are great. ...Read more
Is it possible to get a false positive herpes culture test? How often does it occur? What is the reasoning for it?
Rarely if ever: False positive results are very unlikely for HSV culture. If the test was actually a DNA test (PCR test), there is a slightly higher chance of false pos, but still very unlikely. If you have had a positive culture or PCR, for sure you have herpes at whatever site was tested (genital, oral). But if a blood antibody test, not culture or PCR, false positive results are quite common. Good luck. ...Read more
If doctors swab for a herpes culture, does that mean its a serum test: the more reliable/updated test? What exactly does that mean?
Tested negative for herpes culture test but have symptoms, any other test that I can take that is more accurate? I've had a sore for over 4 months
Boil on leg busted. More bumps appeared on genitals. 2 diff doctors say staph does not look like herpes. Culture shows herpes. Could this be wrong?
Fungal infect or STD? 2 negative herpes culture tests. Jockitch cream cleared up 1st time. Still redness around male urethra and occas spots on shaft
Here are some...: Glad to hear your good response to Jack Itch cream. Since, such creams usually contain anti fungal agent with steroid and direct to suppress and rid skin fungal infection, which inflict warm and moist areas like external genitalia and groins - called tine cruris. For the rashes on penile opening and shaft, you may try the same cream and see if responding in 1 wk. If not, seek pro-evaluation. ...Read more
Very, other tests.: I don't know what your history is but if you had/have a herpes infection, you likely would have noticed skin lesions that could be irritating at some point in time. Many times there can be no symptoms but if you have this there would be some kind of outbreak at some point in time. The tests include tzank prep. Of scrapings that show giant cells, cultures are pos. In 48-96 h, elisa+pcr are great. ...Read more
A test for the virus: A herpes culture is a test performed in a microbiology or virology lab, where they use a swab from a suspicious area and try to "grow out" the herpes virus. This kind of test is notoriously inacurate- and a negative viral culture should not be taken as proof that you don't have the herpes virus. It should be followed up with blood testing to confirm that you have not been exposed to herpes. ...Read more
Probably borderline.: Culture results are usually positive in 48-96 hrs. Elisa and PCR are just as sensitive or more than culture. Seroconversion can document primary infections. A tzanck prep. From lesion scrapings can help make a clinical diagnosis by showing multinucleated giant cells or inclusions by cytology. ...Read more
Fairly Small: Not too likely as a culture is the actual organism itself that was cultured from the patient's lesion in question. Unless it is a mislabeled specimen in the lab as an example. ...Read more
No: However if you get frequent outbreaks you may want to consider taking medicines as a preventative strategy. ...Read more
So if herpes culture only is accurate if organism grows in lab, does that mean someone could have it but it just didn't " grow " at a certain time?
Yes: This is common. The diagnosis is best made clinically, with labs / cultures as an adjunct. ...Read more
Yes: You can have more than one std at the same time. ...Read more
I am currently being treated for genital herpes, culture not back to confirm. I also have a rash on neck, feet, arms. Is this all herpes?
I did viral culture test for herpes with sores from a first outbreak in my MOUTH. Result: positive type 2! Can type be wrong or is really genital???
Herpes: No; Cell culture or PCR test may give a false-negative result if the sores have begun healing or if you are recently infected. It takes several weeks for HSV antibodies to show up in the blood. PCR and cell culture tests show that you have been exposed to the virus at some point. Your doctor may choose to do both or neither based on the physical examination. ...Read more
Possible: Testing in general is accurate, however there are always chances of false negative testing. This can vary from test to test, but generally describes the chance that a reported negative test result is actually positive. Re-testing can help decrease the chances of a false negative test. ...Read more
