Polymerase Chain Reaction (Definition)

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

What should you take when you feel a cold or upper respiratory virus coming on?

What should you take when you feel a cold or upper respiratory virus coming on?

Zinc!: There are many home and tradtional remedies for the common cold, yet little clinical data convincingly supporting one supplement over another. However, clinical studies with human subjects do support zinc lozenges used early in the course of an upper respiratory infection to decrease the length of the illness. Remember to start them early for the best results! ...Read more

What does a high EBV viral nuclear capsid antibody, a high EBV viral capsid antibody IgG and a high IgM EBV viral capsid antibody mean, what's it mean?

Likely immunity,,: You've got antibodies to the ebv which likely means you were infected at some time in your life and you recovered and now your body has circulating antibodies to it. An igg antibody in particular indicates long term resistance. This virus usually causes asymptomatic infection so you probably fought it off and weren't aware of it. Best of luck. ...Read more

Can CMV virus and type 2 diabetes together make the HIV western blot and PCR viral load tests false positive for hiv?

Can CMV virus and type 2 diabetes together make the HIV western blot and PCR viral load tests false positive for hiv?

Yes: A false positive is possible. A test done by a reputable lab is far better than the otc options! false positives can happen even if your health status is perfect! ...Read more

Does VCA IgG value 77.1 u/ml and EBV IgM value less than 10 shows current Epstein Barr Virus infection?

Does VCA IgG value 77.1 u/ml and EBV IgM value less than 10 shows current Epstein Barr Virus infection?

Insufficient: VCA IgG and EBV IgM sometimes are not sufficient to tell, what exactly is going on. More tests may help, for example "D early antigen (EA-D)" and "Epstein Barr nuclear antigen (EBNA)". ...Read more

Does epstein barr virus make a herpes test positive since the EBV is a herpes simplex virus?

No: They are separate viruses that stimulate the production of different antibodies that do not cross react. ...Read more

Could positive epstein barr virus antibodies, with low lymphocyctes be lymphoma?

Could positive epstein barr virus antibodies, with low lymphocyctes be lymphoma?

Not typically: Ebv antibodies indicate prior exposure, and most adults have positive antibodies. Acute ebv infection is mono, with high lymphocytes. Low lymphocyte counts can be due to viral infections or corticosteroid treatment, most commonly. Lymphoma would be unusual. ...Read more

What does a high EBV viral capsid antibody IgG mean?

What does a high EBV viral capsid antibody IgG mean?

Past EBV infection: The presence of igg to the ebv capsule means that your body was exposed at some time in the past to ebv and made antibodies against it. It is at its highest level 2-3 months after the initial infection, and it will always be present. An elevated igm level would be consistent with current/recent infection. ...Read more

What is respiratory syncytial virus?

What is respiratory syncytial virus?

RSV: Rsv is a virus that can infect a person's lungs. Most people have been exposed and infected by age 2. You can be infected more than once. Recovery takes a week or two. Rsv can rarely lead to severe illness requiring hospitalization, especially in infants. ...Read more

VZV IgG titer= 1926, VZV IgM titer >3.91 with reactivated shingles present. What does test mean? Active VZV infection? Is 1926 dangerously high.

VZV IgG titer= 1926, VZV IgM titer >3.91 with  reactivated shingles present. What does  test mean? Active VZV infection? Is  1926 dangerously high.

No it just means: You had chickenpox previously. It is not dangerous at all . The IGm is what tell that you have reactivated and then it is called shingles. You can't have shingles if you did not have chickenpox before. ...Read more

What are the tests for respiratory syncytial virus infection?

What are the tests for respiratory syncytial virus infection?

Nasal mucous: Nasal mucous can be submitted to the lab for identification of the RSV antigen (protein) through immunoflorescent or enzyme immunoassay. These are available in kit form to hospitals & some offices.The test is seldom preformed unless the patient is hospitalized.The test itself does not predict the severity of illness but knowing test results simplifies supportive care as RSV is somewhat predictabl. ...Read more

What does a high EBV viral capsid antibody IgM mean?

What does a high EBV viral capsid antibody IgM mean?

DIAGNOSIS IS MONO:: Acute phase of infectious mononucleosis is characterized by rapid igm and igg antibody response to viral capsid antibody(vca) in all patients. The test may remain positive from 4 weeks, occasionally up to 4 months. ...Read more

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Makes perfect sense: Igm antibodies rise only during the actual, acute infection. They then fade away and are replaced by the various igg antibodies, which are the ones that provide lifetime protection against the same strain of the virus. So your numbers are consistent with the fact you had mono years ago. There is no igm, and positive igg levels. So you are immune and do not currently have mono. ...Read more

HIV NEGATIVE combo (antibody + antigen) tests at 4,6,10,13,14 weeks and PCR RNA VL UNDETECTED (14 weeks) white tongue, chronic pharyngitis. Am I HIV-?

HIV NEGATIVE combo (antibody + antigen) tests at 4,6,10,13,14 weeks and PCR RNA VL UNDETECTED (14 weeks) white tongue, chronic pharyngitis. Am I HIV-?

You are HIV negative: Listen, man. Stop doing this to yourself. Get to an otolaryngologist and see if you have a post-nasal drip, maybe heavy snoring without realizing it, or some actual serious illness. Try scraping the stuff off your tongue with a piece of dental floss; if it's still white patches, ask your dentist's opinion also. But please get over these HIV fears. Maybe even be thankful for having shared love. ...Read more

How is infectious mononucleosis serology interpreted?

How is infectious mononucleosis serology interpreted?

Surprise: When the serology test was first used it was thought to be diagnostic. Eventually it was found that most people were positive. It appears that the eb virus is an opportunist organism that is "waiting in the wings" for some body chemistry that provides its advantage. Then the serology titre (concentrration) goes up as the organism becomes active. ...Read more
