Is hiv-1-pcr quantitative and HIV RNA PCR quantitative same tests?can DNA PCR test be quantitative?
HCV: Nowadays with polymerase chain reaction technology it is making "window" periods a less discussed issue.

For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more

The situation in reality is that no one need wait that long ...Read moreSee 1 more doctor answer
