Yes: The blood tests for both type i and type ii are only intended to support a clinical diagnosis and are not all that sensitive or specific.
Dr. Dennis Higginbotham
Obstetrics and Gynecology 30 years experience
Depends: When a person initially contracts herpes, the blood test will be negative. After the body has mounted an immune response, which may take 6 to 8 weeks, the blood test will become positive and will always be positive.

A 41-year-old member asked:

What can cause genital herpes without having any type of sexual contact?

Any Direct Contact: Genital herpes is essentially spread by direct contact with an infectious area. It is very common and easy spread. Genital herpes can be spread even if you or your partner don't see any sores - orally or genitally. Valtrex (valacyclovir) has been shown to reduce, not eliminate the risk for asymptomatic transmission. Condoms can help but contact outside of the condom covered areas can result in infection.

With fingersticks: If the hands and fingers aren't clean and dry, home blood sugar readings may be inaccurate. Sugar on the fingers could end up falsely elevating blood sugar. A concomitant venous sample in lab could demonstrate a discrepancy. Also, the meter may be inaccurate. Eating before a fasting blood sugar may raise the blood sugar in someone with diabetes because it would not be fasting anymore.

Can l-arginine lower blood pressure & if so what is recommended dosage?

Possibly beneficial: In some people. Arginine is converted to nitric oxide, which has a relaxing effect on blood vessels & can thus reduce blood pressure somewhat. No standardized dose has been recommended. Be advised that arginine can also trigger or worsen viral infections like herpes. Discuss this supplement with your doc before taking it.
