[Use of the diffuse precipitation reaction for detecting anti-rotavirus antibodies in children].

: Antirotaviral antibodies have been detected by the diffuse precipitation test in 16% of 355 patients with acute intestinal infections aged 1 month to 14 years; specific coproantibodies have been detected in 1.4% of 138 patients. The authors emphasize the specificity and simplicity, though a lower sensitivity of the diffuse precipitation vs. the neutralization test.
