Will a newborn screening test show positive for cystic fibrosis if only one parent is a carrier?
A newborn screening test for cystic fibrosis typically detects the presence of elevated levels of immunoreactive trypsinogen (IRT) in the blood, which can indicate the condition. However, a newborn can only have cystic fibrosis if both parents are carriers of the defective CFTR gene. If only one parent is a carrier, the child will not inherit the disease, but may still be tested as a carrier. Therefore, a positive newborn screening result may indicate the need for further testing to confirm the diagnosis.

Neonatal cystic fibrosis screening?
DefinitionNeonatal cystic fibrosis screening is a blood test that looks for increased levels of immunoreactive trypsinogen (IRT), an enzyme produced by the pancreas. The test is performed on newborns to screen for cystic fibrosis (CF).Alternative NamesCystic fibrosis screening - neonatal; Immunoreactive trypsinogen; IRT testHow the test is performedA sample of blood is either taken from the bottom of the baby's foot of a vein in the arm. A tiny drop of blood is collected onto a piece of filter paper and allowed to dry. The dried blood sample is sent to a lab for analysis.How to prepare for the testThere is no special preparation needed.Some states include this test in the routine newborn screening tests that are done before the baby leaves the hospital.If you live in a state that does not perform routine CF screening, your health care provider will explain whether testing is needed.How the test will feelThe brief feeling of discomfort will probably cause your baby to cry.Why the test is performedChildren with CF who are diagnosed early in life and start treatment at a young age may have better nutrition, growth, and lung function. Newborn screening tests allow doctors to identify children with CF before they have symptoms.Normal ValuesNormal values vary from lab to lab. Ask your doctor or testing center for details.What abnormal results meanIt is important to remember that a positive screening test for cystic fibrosis does not diagnose cystic fibrosis. If your child's test is positive, further tests will be done to confirm the possibility of CF. Not all children with a positive screening IRT test have CF.What the risks areRisks associated with the test include:Infection (a slight risk any time the skin is broken)Anxiety over false positive testsFalse reassurance over false negative testsSpecial considerationsThe IRT level does not indicate the severity of the CF. False-positives may occur.ReferencesFarrell PM, Rosenstein BJ, White TB, et al. Guidelines for diagnosis of cystic fibrosis in newborns through older adults: Cystic fibrosis consensus report.

Is LC MS more reliable test for Newborn screening or is it GC MS?
LCMS (actually) LCMS/MS goes the half way for newborn screening. Its then the GCMS which comes for rescue. It clarifies the results given by LCMS and says with accuracy whether it is a positive or a negative case, against what was indicated in the LCMS screening. GCMS is mostly based on urine sample while LCMS needs blood spots. Thats where GCMS already scores a big point above LCMS. Further, GCMS "confirms" a disorder, while LCMS stops at "maybe". GCMS tests for a massive range of disorders while LCMS is limited to a few class of disorders. GCMS is the future of screening, while LCMS is the present of screening.
