There are 249 molecular diagnostic tests as of March 6, 2021, including 38 at-home versions (one of these you can buy over-the-counter).  These tests will tell you if you have an active COVID-19 infection. There are 15 antigen tests that also are used for diagnosing COVID-19. For at-home options, the test will be sent to you at your home after you complete an online questionnaire, or you may get a prescription for one and take it and get the results at home within minutes without needing to send a sample to a laboratory for analysis.

FDA List of Emergency Use Authorized Antibody Tests
As of March 6, 2021, there are 72 individually authorized serology tests, including at least two that estimate the level of antibodies, not just the presence of them, and one that tests for the presence of "neutralizing" antibodies.

FDA Frequently Asked Questions about Antibody Tests

The FDA answers common questions about serology testing, noting that "researchers do not know whether the presence of antibodies means that you are immune to the coronavirus in the future; or if you are immune, how long it will last."

Drugs and Treatments for COVID-19

NIH Official Treatment Guidelines
This page from the National Institutes of Health outlines the guidance for each level of infection: from asymptomatic (or presymptomatic) to the most severe. Because no drug has been officially approved to treat COVID-19, all of the treatments are considered to be under investigation.

This site recruits and provides information to vaccine trial volunteers. It includes information on what to expect when you volunteer. As of 25 January, 2021, it describes two investigational vaccine trials that are actively recruiting volunteers in the U.S. Sponsors are Eli Lilly and Novavax.

Blood and Plasma Donation Opportunities

In August 2020, the  FDA had given Emergency Use Authorization for convalescent treatment for Covid-19, but the authorization was scaled back in February 2021:
On February 4, 2021, the FDA revised the convalescent plasma EUA to limit the authorization to high-titer COVID-19 convalescent plasma and only for the treatment of hospitalized patients with COVID-19 early in the disease course or hospitalized patients who have impaired humoral immunity.

Volunteer to Donate Blood or Blood Plasma:  AABB Blood Bank Locator
Blood donations in the U.S. have decreased due to the implementation of social distancing and the cancellation of blood drives. Health experts say that donating blood by appointment is safe.

Volunteer to Donate Blood or Blood Plasma: American Red Cross
The American Red Cross collects blood, platelet, and plasma donations. It provides antibody testing for all donors. Other locations, like hospitals, may not offer to perform the antibody test when you donate blood, since the infection has not been proven to be transmitted through blood transfusion. If you donate blood or plasma before June 28, 2021, you will receive free antibody testing by the Red Cross.

Volunteer to Donate Convalescent Plasma: National COVID-19 Convalescent Plasma Project
If you have fully recovered from COVID-19, you may consider donating your blood plasma. Because it contains antibodies to the virus, the plasma may be used as a treatment for those sick with COVID-19. Many hospitals, clinics, and blood donation centers are accepting donations.
