Today a culture exam is performed in 97 percent of all patients. However, questions remain about the completeness and reliability of the resulting data since not all of the patients have positive culture results, and the quality of the samples is not 100 percent reliable.
Data from some parts of the Russian Federation also are not very reliable, according to Skachkova, especially where laboratory capacity is lacking. As this capacity is increased, incidence rates will increase as well. And with an overall incidence of MDR TB of 4 per 100,000 population, the rate of new cases remains significantly higher than the national goal of 1.5 per 100,000 population.
