SUNDAY, January 8 (HealthDay News) -- Revised rules that could
make herpes virus tests cheaper and more widely available have been
proposed by the U.S. Food and Drug Administration.
In a proposal released Friday but dated Dec. 21, the FDA said it
may change the classification of tests for herpes simplex virus
types 1 and 2 to class II from class III, which would reduce the
regulatory burdens associated with the tests, the Associated Press
The change would open the way for companies seeking to develop
and market herpes tests and would also relax the training
requirements for laboratories and medical offices that offer the
tests, FDA spokeswoman Julie Zawisza said.
The FDA considered reclassifying the tests as long ago as 1980,
but said the tests posed a "potential unreasonable risk of illness
or injury" at the time. With the older tests, a false positive

You've been diagnosed with genital herpes and now you and your long term partner are asking the inevitable questions: Was someone unfaithful? If he or she has herpes, do I? If I don't, how can I keep from getting it? First, stop speculating about your partners actions. In many cases, it's a futile effort. The primary infection - as it's called - can cause typical outbreak symptoms or it can be totally asymptomatic. After initial infection, the virus climbs up a nerve where it can lie dormant for days, weeks, months or even several years. Knowing when, how or from whom you got the virus can be very difficult to figure out. Deal with where you are now. And that means that the unaffected partner needs to be tested as soon as possible to see if they are infected. Know that there are many different tests that your doctor may order to screen for herpes. One test screens for both forms of herpes. Therefore if you are positive, you don't know which one you have. ...
Fetal scalp pH testing is a vaginal procedure performed when a woman is in active labor to determine if the baby is getting enough oxygen.

How the test is performed
The procedure typically takes about 5 minutes. The mother lies on her back with her feet in stirrups. If her cervix is dilated at least 3 to 4 centimeters, a plastic cone is placed in the vagina and fit snugly against the scalp of the fetus.
The scalp of the fetus is cleansed and pierced, and a small blood sample is taken for examination. The blood is collected in a thin tube. The tube is either sent to the hospital laboratory or analyzed by a machine in the labor and delivery department. In either case, results are available in just a few minutes.
If the woman's cervix is not dilated enough, it is impossible to perform this test.
