Summary
David Friedberg made a compound prediction for the U.S.:
- RT‑PCR testing backlogs and scaling problems would be “over the first hump” in roughly 7–10 days from March 18–19, 2020 (i.e., by about March 25–29).
- Broad, general‑population antibody testing would begin roughly 30–45 days after that, i.e., about 45 days from the recording date (late April–early May 2020).
Outcome: the PCR‑testing part was clearly wrong, while the antibody‑testing timeline was roughly right. Because the prediction was framed as a single combined forecast (“so call it 45 days out”), the overall result is best classified as wrong, though with an important correct subcomponent.
1. RT‑PCR backlog & scaling in the U.S. (7–10 days)
What he predicted: that the acute backlog and scaling issues around RT‑PCR testing would be largely resolved within 7–10 days of March 18–19, 2020.
What actually happened:
- A national survey of 323 U.S. hospitals conducted March 23–27, 2020 (right in that 7–10‑day window) by the HHS Office of Inspector General found:
- “Severe shortages of testing supplies and extended waits for test results” that limited hospitals’ ability to monitor patients and staff.
- Hospitals frequently waited 7 days or longer for test results, and shortages of swabs, media, and reagents meant hospitals “were unable to keep up with testing demands.” (oig.hhs.gov)
- The same report summarized that hospitals’ “most significant challenges” included testing shortages and long turnaround times, not a resolved situation. (medicaleconomics.com)
- Large commercial labs illustrate the ongoing backlog:
- Quest Diagnostics reported that as of March 25, 2020 it had a backlog of ~160,000 tests awaiting processing. (orthospinenews.com)
- In an April 1 media statement, Quest said it ended March with capacity >30,000 tests/day but still had a backlog of 115,000 tests, with average turnaround times of 4–5 days (2–3 days for prioritized patients). (marketscreener.com)
- An NPR report on April 3, 2020 described Quest’s backlog being cut from 160,000 to 115,000 in late March but still characterized national testing as plagued by backlogs and 4–5‑day result times. (news.wjct.org)
In other words, during and even after the 7–10‑day window, U.S. RT‑PCR testing was still experiencing severe shortages, long delays, and large lab backlogs. Backlogs at major labs were only reported as eliminated around mid‑April, not late March. (marketscreener.com)
Assessment for part (1): The U.S. had not “gotten over the first hump” of PCR testing by March 25–29, 2020. Backlogs and bottlenecks remained severe. This part of the prediction was wrong on timing and severity.
2. Broad general‑population antibody testing (≈45 days out)
What he predicted: that after the PCR “first hump,” it would take another 30–45 days to get antibody tests “more broadly distributed” for general‑population testing, i.e., roughly late April to early May 2020.
What actually happened:
- The first FDA Emergency Use Authorization (EUA) for a COVID‑19 antibody (serology) test was issued to Cellex on April 1, 2020. (fda.gov) This enabled clinical labs to begin serology testing but did not yet constitute broad consumer availability.
- Through April, multiple additional antibody tests (e.g., from Abbott, Ortho, others) received EUAs, creating a growing supply of lab‑based serology tests in the U.S. (en.wikipedia.org)
- Broad, walk‑in consumer access began in late April:
- On April 28, 2020, Quest Diagnostics launched a consumer‑initiated COVID‑19 antibody test through QuestDirect, explicitly marketed as allowing individuals to purchase an antibody test without visiting a doctor’s office, with blood draws at 2,200 patient service centers nationwide. The company’s release states that this service “broadens access to COVID-19 antibody testing in the United States” and that “individuals can purchase COVID‑19 antibody testing for themselves online.” (newsroom.questdiagnostics.com)
- Contemporary coverage summarized this as: “For about $120, anyone can now get a COVID-19 antibody test from Quest Diagnostics,” emphasizing no doctor referral and nationwide access via Quest’s centers. (fiercehealthcare.com)
- User reports from late April and early May 2020 show ordinary people scheduling and obtaining these Quest antibody tests directly, supporting that general‑population access was underway by then. (reddit.com)
Counting from March 19, April 28, 2020 is about 40 days later, squarely inside Friedberg’s 30–45‑day window for the start of broad general‑population antibody testing. The timing and nature of Quest’s national rollout, plus multiple EUA‑backed serology platforms in April, match his description well: not perfect saturation, but the beginning of broad, consumer‑level distribution.
Assessment for part (2): His forecast that broad antibody testing for the general population would start roughly 30–45 days after mid‑March was substantially correct on timing and general character.
Overall judgment
Because Friedberg’s statement bundled these together—first, PCR backlogs clearing in ~7–10 days, then broad antibody testing ~30–45 days later—the PCR component was decisively wrong, while the antibody‑testing timing was quite accurate.
Given that the acute PCR backlog/scaling problem did not resolve within his 7–10‑day window and remained a major national constraint into April, the combined prediction did not come true as stated.
Overall result: wrong, with the important nuance that his antibody‑testing timeline was basically right, but his near‑term optimism on PCR backlogs was not.
