Alternatively, you can use a standard newborn screening collection card. 1 val. Objectives: To evaluate the timing of a delayed rise in thyroid-stimulating hormone (TSH) levels in preterm infants with congenital hypothyroidism, and to determine whether cases of congenital hypothyroidism would be missed by using current consensus guidelines of repeat screening at approximately 2 weeks of age or 2 weeks after the first screening Tests may need to be repeated for a number of reasons including being improperly collected, the infant received a blood transfusion, the specimen was collected when the baby was less than 24 hours of age or a possible disorder is indicated. As part of the blood screening, doctors measure the T cell receptor excision circles, or TRECs, and the TREC screening results are either normal or abnormal.

The EnLite Neonatal TREC Kit is an in vitro diagnostic device intended for the semi-quantitative determination of TREC (T-cell receptor excision circle) DNA in blood specimens dried on filter paper. Newborn screening identifies conditions that can affect a child's long-term health or survival. As of May 2015, about 70% of all newborn babies in the US are screened for SCID. 6 copies with an ACTB > 700 copies with sensitivity of 100% for TREC and 97% for KREC. Rarely low TREC can be caused by destruction of T cells as seen in neonatal leukemia and some forms of acute HIV infection. Newborn screening for severe combined immunodeficiency (SCID) was instituted in California in 2010. The sensitivity of TREC based NBS for typical SCID was 100 %. Approximately, 1 in 20,000 babies have low T cells based on the data from newborn screening.

Newborn Screening Clinical Care Coordination Question: What do we do if a baby has an unsatisfactory screen, but we are unable to get the baby back in for another one after multiple attempts to contact/notify the parent/guardian? In recent years, different screening algorithms for TREC based SCID screening were reported. Adapting the screening algorithm for pre-term/ill infants reduces the amount of false positive test results. Newborn screening is a public health program designed to screen infants shortly after birth for conditions that are treatable, but not clinically evident in the newborn period. All infants born in Tennessee should have the newborn screening filter paper collected prior to leaving the hospital. The numbers of TRECs were enumerated by real-time quantitative polymerase chain reaction from NBS cards, and a cutoff value of less than 25 TRECs/L with a normal -actin level constituted an abnormal test. Jennifer L. Taylor, PhD. TREC SCREENING. The TREC cut-off score determines the percentage of non-SCID TCL cases detected in newborn screening for TCL. For ease of reporting, similar analytes are reported together as Profiles.
