Errors occurred in the article by Ahmed A et al titled “Interferon-γ Release Assays in Children <15 Years of Age” published in the January 2020 issue of Pediatrics (2020;145[1]: e20191930. doi:10.1542/peds.2019-1930).

On page 4, the Progression to Disease begins, “Four children developed culture confirmed pulmonary tuberculosis during a median follow-up of 4.3 years (interquartile range: 3.2–5.0). Two were 7-month-old US born twins exposed to a common source. Both twins developed tuberculosis disease 2 months after enrollment. The twin with all negative…” This should have read, “Four children developed pulmonary tuberculosis during a median follow-up of 4.3 years (interquartile range: 3.2–5.0); 3 of these were culture positive. Two of the cases were 7-month-old US-born twins exposed to a common source; 1 had a culture-positive gastric aspirate, and the other twin’s gastric aspirate was culture negative. The twin with all negative…”

On page 7, in Table 3, for the twin with negative TST/QFT/TSpot results (row 1), the last column reads, “Gastric aspirate culture positive result.” This should have read, “Gastric aspirate culture-negative result.”

On page 8 (second column, third paragraph), the sentence begins, “Strengths of this study include (1) a large cohort of children <5 years old; (2) data on outcomes for .500 untreated children with TST-positive, IGRA-negative results; (3) inclusion of all commercially available tests for LTBI; and (4) culture confirmation of all cases.” This should have read, “Strengths of this study include (1) a large cohort of children <5 years old; (2) data on outcomes for >500 untreated children with TST-positive, IGRA-negative results; and (3) inclusion of all commercially available tests for LTBI.”

The above corrections have been made to the online article.
