title: [Lipoprotein-x determination in children beyond an age of 6 months (author's transl)].
abstract: In premature and newborn infants an abnormal lipoprotein (LP-X) was almost regularly detectable by examination up to the 24th week after deliver. The aim of the submitted study was to evaluate LP-X results in children older than 6 months. 250 sera of 158 infants of all age groups were tested for presence of LP-X. The frequency of LP-X positive results was 85.7% in the group of infants younger than 24 weeks (91 samples of 45 infants were tested) whereas in the group of infants of an age between 24 weeks and 14 years (159 samples of 113 children were tested) 16.35% positive results were obtained. LP-X positive results showed the same clinical significance in the second group of children as it was demonstrated in adults elsewhere.
