The Slovak Antimonopoly Office (PMU) has imposed fines totaling nearly €15 million on a cartel comprising four medical laboratories and an industry association. The ruling follows an extensive investigation into anti-competitive conduct within the laboratory diagnostics sector, which officials say impacted services across Slovakia.
The decision, announced during a press conference on Tuesday, targets entities that allegedly manipulated the market for diagnostic services. According to the PMU, the participants engaged in coordinated efforts to fix prices and divide customers, undermining fair competition in a critical area of public health. This Slovak medical laboratory cartel operated both before and during the COVID-19 pandemic, a period of heightened demand for diagnostic testing.
Because the case involved complex coordination and sensitive health data, the resulting administrative decision spanned 370 pages. While the fines are substantial, the PMU noted that the decision is currently first-instance and non-final, as the majority of the penalized entities have already filed appeals.
Scope of Anti-Competitive Conduct
The investigation revealed a systematic effort by the laboratories and their association to eliminate competition. Juraj Syrny, the head of the PMU’s cartel department, detailed the specific mechanisms used by the participants to maintain their grip on the market. The group reportedly agreed on prices and other terms and conditions, effectively removing the incentive for competitive pricing in laboratory diagnostics.
Beyond price-fixing, the cartel engaged in market and customer allocation, ensuring that the participating laboratories did not compete for the same clients. The PMU found that the entities coordinated their actions during public procurement processes and exchanged sensitive information to synchronize their bids and offerings. These actions are cited as a direct violation of competition laws designed to protect consumers and the state from inflated costs.
Timeline of the Investigation
The path to the €15 million penalty began in 2023, when the Finance Ministry’s Value for Money Unit identified suspicious behavior. The unit warned of irregularities in how major medical laboratories were signing contracts with health insurers, which served as the catalyst for the PMU’s intervention. This warning triggered a series of inspections that eventually led to the formal launch of administrative proceedings in 2024 according to the Antimonopoly Office.
The complexity of the case required nearly two years of investigation to complete. The probe focused on the intersection of private corporate interests and public health funding, particularly looking at how the cartel’s behavior persisted through the volatility of the COVID-19 pandemic. The final 370-page decision reflects the scale of the evidence gathered during this period.
Penalties and Legal Framework
The PMU applied a rigorous penalty structure to reflect the seriousness of the market manipulation. Peter Demcak, the vice-chair of the PMU, stated that the office utilized the maximum lengths permitted by law to deter future anti-competitive behavior. This included imposing fines of up to 10 percent of the entities’ global turnover and applying the strictest degree of gravity, valued at 30 percent, as permitted by Slovak regulations as stated by Peter Demcak.

In addition to the financial penalties, the PMU has banned most of the involved entities from participating in public procurement procedures for a period of three years. This ban prevents the laboratories from bidding on state contracts, which are a primary source of revenue for diagnostic providers.
Not all participants received the same penalties. One entity involved in the cartel cooperated with the PMU during the investigation, leading to a reduction in its specific fine. This leniency program is a standard tool used by antitrust authorities to encourage cartel members to come forward with evidence.
What This Means for the Healthcare Sector
The crackdown on the Slovak medical laboratory cartel highlights the vulnerability of healthcare diagnostics to price-fixing, especially during public health crises. When laboratories coordinate prices and divide customers, the cost of diagnostics typically rises, potentially increasing the burden on health insurers and, by extension, the taxpayers and patients.

The involvement of the Finance Ministry’s Value for Money Unit suggests a broader effort by the Slovak government to increase transparency in public spending and ensure that health-insurer contracts are awarded based on merit and cost-effectiveness rather than collusive agreements.
The current status of the case remains in the appeals phase. Because most of the laboratories have challenged the ruling, the final financial obligations and the duration of the procurement bans may be subject to further judicial review.
The next confirmed checkpoint for this case will be the judicial proceedings regarding the appeals filed by the affected laboratories. Official updates on these filings and the subsequent court rulings will be provided by the Antimonopoly Office as the legal process continues.
