I cannot create a summary of the requested article because the article titled "Effort to Fix Harms of Race-Based Kidney Testing Helps Black Transplant Candidates" from MedPage Today is not found in the search results provided. The available results contain information about kidney transplantation in Slovakia, including compatibility procedures, patient preparation and experimental pig kidney transplants, but not the article you requested to summarize. In order to create an accurate and factual summary, I would need access to the full text of said article.
