Определение активности АДА (более пороговой величины в 30 ед/л) имело чувствительность и специфичность теста 95 и 94% соответственно. Чувствительность определения активности АДА-1 и АДА-2 (более пороговой величины более 20 ед/л) составила 30 и 93% при специфичности 96 и 88% соответственно. Частота выявления активности АДА и АДА-2 выше пороговой величины не зависела от клеточного характера туберкулезного плеврита.

The sensitivity of testing the activity of ADA-1 and ADA-2 (above the threshold value of 20 u/L) was 30 and 93% with the specificity of 96% and 88%, respectively.
