Newborn disease screening test items and precautions, parents quickly understand it!

Neonatal screening is a simple, fast and heel prick test inexpensive blood spot test that allows early detection of congenital genetic diseases in children and timely treatment for healthy growth.

Caution.

Blood collection time is generally 72 hours to 7 days after birth and after adequate breastfeeding; for premature babies, low birth weight babies, newborns with diseases and newborns discharged early, blood collection time should not exceed 20 days after birth.

The vast majority of infants have normal screening results, which are kept on file and are not communicated to the parents.

Only if a suspicious positive or positive result is found will the screening center notify the parents, provide further confirmation or differential diagnosis of the infant, and provide treatment and intervention as soon as possible after the diagnosis is confirmed.

Screening process

(1) Screening site: The blood collection site is the inner and outer heel of the newborn;

(2) Screening time: The blood collection time is 72 hours after the birth of the newborn family.

The reasons for collecting blood after 72 hours are as follows.

(1) Blood should be collected 72 hours after birth and 6 times after feeding; otherwise, in the case of no feeding and no protein load, screening false negatives are likely to occur;

(2) Blood collection 72 hours after birth can reduce the chance of false positives in disease screening, avoid the rise of physiological thyroid stimulating hormone, and prevent delayed thyroid stimulating hormone false negatives.

(3) For infants discharged early or transferred to other hospitals for various reasons, if blood cannot be collected after 72 hours, in principle, blood should be collected by the receiving unit for follow-up of the above infants to improve the screening coverage, but the time should not exceed one month after birth at the latest.
