Instead of schlepping to the doctor's office or the lab, you may one day be able to check your HIV viral load (VL) at home. British scientists are developing a finger-prick blood test—similar to the tests people with diabetes use to keep an eye on their insulin levels—that could be ready to start clinical trials in three years. Such a test could also help in rural and remote areas, providing an (ahem) at-hand, affordable way to monitor HIV-positive people's health—and offer an incentive to take the meds that keep those VLs low.
