Hi i want to know risks associated with ear tags of a new born. amniocentesis was done during pregnancy and was fine, does this rule out any risk?

Yes, but others exis: Pre-auricular tags are seen familially, sporadically, or syndromically (e.g. Holt-oram, goldenhaar). A pediatric geneticist should examine the infant in detail and a chromosomal microarray analysis performed, if not done on the amniocentesis sample. Prenatal negative testing typically excludes major chromosomal defects, but not small ones. Good luck!

Confusing question: Amniocentesis will rule out only the issues where studies were done.The most common would be the typical chromosome defects. There are hundreds of metabolic defects, Amino Acid disorders, storage diseases, that could be studied by amnio, but the studies must be pre-arranged and may only be done at selective labs.The studies can eliminate some worries, but are not 100% exclusive of any possible pbm.

Ear tags: Most ear tags are benign and not associated with any abnormalities. One thing i know they can be associated with is hearing abnormalities. Hearing test in the hospital and subsequent one later in life (consult with ent) is important to conduct. Otherwise, no other testing than routine one in the hospital (metabolic profile) is recommended.
