WADA Expands Sample Testing, Yet Momentum Is Slowing Ahead of the 2027 Code

It was 4:50 in the morning, and Long Bien Bridge was still wrapped in mist. I stood at the eastern railing, a recorder in my coat pocket, waiting for Nguyen Van Lai to run past. He usually trains at this hour, before the city wakes. But that morning I had not come to ask about steeplechase technique. I had come to ask something I had been holding in my head for weeks: did he know when he would be called for a doping test?

Lai smiled. "I don't need to know. I only need to know I'm clean."

That is an athlete's answer. But when I read the 2026 annual report of the World Anti-Doping Agency (WADA), I realized that my question and Lai's answer sit on two sides of a system under unprecedented pressure. Some races are not measured by a stopwatch, but by the silence between two breaths.

WADA was founded in 2026 with the backing of the International Olympic Committee (IOC) and governments, and coordinates anti-doping rules and standards worldwide. The 2026 annual report is not about a single sport. It is a governance report, compiling testing data, the compliance status of national anti-doping organizations, financial conditions, and progress toward the 2027 World Anti-Doping Code.

For Vietnamese swimming fans, this document may seem remote. But it directly shapes the competitive conditions of every athlete, from a young swimmer in Da Nang to an Olympic champion in Paris.

The report records 297,965 tests in 2026, up from 288,865 in 2026 — roughly 9,100 additional samples. Reading the headline "WADA increases sample testing," one easily pictures a steadily rising curve. But the data inside tell a different story.

Growth has decelerated sharply. From 2026 to 2026, test volume rose 12.5 percent. From 2026 to 2026, it rose only 3.2 percent. This is a decelerating curve, not an accelerating one. Meanwhile, the Adverse Analytical Finding (AAF) rate — the formal term for a positive test — has barely moved in three years: 0.77 percent in 2026, 0.80 percent in 2026 and 0.78 percent in 2026. The band of variation is only about 0.03 percentage points.

For someone who has spent years watching testing at regional swimming meets, this stability carries two opposite meanings. On one hand, it may reflect a genuinely stable doping prevalence below one percent. On the other, it may reflect a testing system expanding its coverage without yet reaching the truly dark zones. The data alone cannot separate the two.

Why does this matter for swimming? Because swimming is a testing-intensive sport, with multiple distances, relays and congested calendars. A testing system slowing at the global level will cascade down to the national level, and resource-limited countries like Vietnam are usually the first to feel the decline.

The second notable point is compliance. The report says the average number of non-conformities in compliance audits fell from 25.5 to 20. But that comparison rests on only nine audits — too small a sample to be representative. More worryingly, non-conformities related to testing itself rose 11 percent year on year, accounting for 45 percent of all findings, with 23 percent classified as critical. In other words, the overall picture looks better, but the core weakness is worsening.

That is a paradox anyone who has worked in sport recognizes. When a national anti-doping organization lacks the capacity to collect samples, the consequence does not fall on a desk. It falls on the athlete. A swimmer in a country without adequate testing has no one to protect their clean record with a complete biological passport. And when they suddenly shine on the international stage, suspicion appears automatically — however clean they may be.

I once saw this from another angle. In 2026, at Bukit Jalil Stadium in Kuala Lumpur, I ran down to the track to interview Nguyen Thi Huyen right after she won 400m hurdles gold in 56.14 seconds, her sweat still wet. Three weeks later I dug through old data and found she had suffered a serious injury in 2026 and nearly retired. Huyen crossed the finish line, and I crossed a boundary in my own journalism. But behind that moment lay another question: if an athlete must prove their innocence without sufficient testing records, is their achievement truly protected?

Meanwhile, WADA's financial system is showing cracks. The budget came in $8.3 million below plan. The United States underpaid by $3.8 million, and Russia owes $3.9 million. The only bright spot is a net surplus of $1.2 million. The coexistence of a large shortfall and a small surplus suggests aggressive cost-cutting or deferred spending. And when an organization must cut costs, the investment cut is rarely communications — it is operations.

For a sports journalist in Vietnam, this raises a practical question. As WADA shifts from "traditional testing first" to "investigations and prevention," how much resource will laboratories and national organizations in smaller countries receive? The report cites more than 250 investigation operations, 88 laboratories dismantled, and over 90 tons of substances seized. These are impressive results. But they come from investigations targeting large networks, not from increasing sample frequency at a youth swimming meet in Southeast Asia.

WADA also adopted the 2027 World Anti-Doping Code in Busan, South Korea. It takes effect on January 1, 2027. This is a fixed milestone with clear planning value for every federation. Before the new code takes effect, 2026–2026 will be a compliance gap, as national organizations keep old habits while waiting for the new rules. For developing countries, this gap is especially dangerous, because they are usually the slowest to adapt.

The third notable point is consultation. WADA and the Athlete Council held an athlete-centered consultation involving more than 600 athletes and commissions from over 60 countries and more than 70 sports. This is a commendable legitimacy-building effort. But the report does not say whether athlete voices actually changed the substance of the Code. A broad consultation without measurable outcomes is still just a consultation.

Here I want to state plainly what most WADA coverage skips. The headline "WADA increases sample testing" is not wrong, but it conceals a more important truth: growth momentum is fading, the detection rate is flat, and the most serious weakness lies in sample collection itself — not in sample volume.

In 14 years of covering sport, I have learned that real crises rarely come from big shocks. They come from quiet erosion. A system can announce 9,100 additional tests a year and still be weakening, if those tests do not reach the right places at the right times. Based on my experience covering competitions, I believe the biggest gap is not one of quantity but of allocation.

When I asked Nguyen Van Lai whether he worried about being inadequately tested, he said: "What I fear is not being tested. It is being suspected with nothing to prove." In silence, an athlete's heart beats louder than any cheer.

The common framing — more tests mean cleaner sport — is a thinking trap. It assumes the problem is quantity, when the real problem is quality and allocation. A system doing 300,000 tests but missing the weakest countries will be less effective than one doing 200,000 tests but covering the right hotspots. This is a counterintuitive conclusion, because it runs against a media instinct: we tend to measure seriousness by scale rather than precision.

And here is the second blind spot: people tend to treat WADA as an absolutely powerful body. In reality, WADA does not collect samples itself. It sets rules, audits and coordinates — but enforcement lies with national anti-doping organizations and federations. When the United States underpays by $3.8 million and Russia owes $3.9 million, the question is no longer about rules, but about who pays to enforce them. A rule-setting body that does not control its enforcement budget depends on the goodwill of others.

For Vietnamese swimming, the consequences could be very concrete. If major nations stop contributing, WADA must prioritize "high-yield" investigations where doping networks are clear, rather than maintaining steady testing frequency in lower-risk sports like swimming. That means a Vietnamese swimmer may be tested less out of competition, not more. And in sport, less testing is never good news for the clean.

There is one small detail in the report I think many will overlook: the AAF rate, though flat, is the most stable indicator in the entire document. Three years, three nearly identical values. That stability has its own value. It shows the detection system is operating consistently despite changing scale. It is a baseline for future comparison, not a worrying signal. But it also raises another question: if the detection rate does not change while test volume rises, does increasing volume really yield more new findings, or does it merely test more people who were already clean?

The empty stands of 2026 taught me that sport never goes silent — it only changes its voice. The same is true of the anti-doping system. It does not disappear when its budget is cut. It shifts into forms that are less effective, less comprehensive and less fair.

I think of Nguyen Van Lai, still running up Long Bien Bridge at 5 a.m. every day, not needing to know whether he will be tested. His cleanliness does not depend on whether anyone is watching. But the ability to prove that cleanliness does depend on a system — and that system needs strengthening, not just expansion.

When Karsten Warholm broke the 400m hurdles world record in 45.94 seconds in Tokyo in the summer of 2026, I stood at the third bend and nearly screamed from the press seats. That achievement only has value if it exists within a system where every athlete is treated equally. The finish line is where the performance ends. But the race that gives that performance meaning has only just begun.

The 2027 Code takes effect on January 1, 2027. Between now and then, the biggest question is not how many rules WADA will add, but whether nations will have the resources to enforce them. If the answer is no, then every discussion about fairness in sport remains only theory.
