COVID-19: What You Need to Know About Antibody Testing
As the number of COVID-19 cases in the U.S. surpasses 800,000, many Americans want to know if recovered patients have immunity to the novel coronavirus.
The answer could come from an antibody test.
Antibody tests measure the number of antibodies – proteins made by plasma cells – in the blood. The body's immune system uses antibodies to neutralize pathogens such as viruses and bacteria.
While these tests are commonly used to tell if someone is immune to diseases such as measles or chickenpox, they're not yet widely available for COVID-19. But it's not clear what the results would mean, said infectious disease specialist Rekha Murthy, MD, vice president of Medical Affairs and associate chief medical officer at Cedars-Sinai.

Dr. Laxmi Mehta, a cardiologist at The Ohio State University Wexner Medical Center, chaired the statement, which described how cardio-obstetrics has become an important team in managing heart-related problems during pregnancy.

New American Academy of Dermatology Survey Finds Most Americans Know Sun Protection is Important, Yet Many Aren't Protecting Themselves
In recognition of Skin Cancer Awareness Month in May, dermatologists remind the public to #PracticeSafeSun to reduce their risk of skin cancer
As more Americans head outdoors for warmer weather and fresh air amid “shelter-in-place” measures, dermatologists from the American Academy of Dermatology have an important reminder: practice safe sun. Skin cancer is one of the most preventable types of cancer, but new data from the AAD shows that many Americans aren’t taking the necessary steps to protect themselves.
According to a recent AAD survey, 76% of Americans agree that sun protection is an important healthy habit, yet only 41% report regularly protecting themselves outdoors — increasing their risk for skin cancer. While exposure to the sun’s harmful ultraviolet (UV) rays is the most preventable risk factor for skin cancer, the survey also revealed that 28% of Americans admit they rarel
