Record 2 2010-02-05

English

Subject field(s)
  • Genetics
CONT

TPP has received applications from CBS and HQ(Héma-Québec) to begin genomic amplification testing/nucleic acid testing(GAT)/NAT).

CONT

Nucleic acid testing, called NAT by blood banks, promises to close that gap. It could virtually eliminate the few cases of HIV that taint blood every year, said Dr. Celso Bianco of the New York Blood Center. And experts predict it will prevent an estimated 84 annual cases of hepatitis C transmission through blood, the vast majority. The government hasn’t mandated NAT-tested blood yet because technically it's still experimental. Genetic fingerprinting is commonplace in laboratories, where it's called PCR, for polymerase chain reaction testing. But how to test the entire blood supply raises questions, and blood banks are using different strategies to implement the new technology.

French

Record 3 2009-03-30

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Biochemistry
CONT

Nucleic acid amplification tests are the most complex and sensitive of the nucleic acid testing technologies. They use enzymes to amplify the target nucleic acid and most are theoretically capable of detecting in a sample a single nucleic acid molecule. Most of the nucleic acid amplification tests use nucleic acid probes to identify the resulting amplified material.

CONT

Nucleic acid amplification tests (NAATs) are the most sensitive tests for the screening and diagnosis of genital chlamydial infections ... That NAATs can be used with noninvasively collected specimens, such as first-catch urine samples (FCU) from men or women and self- or clinician-collected vaginal swabs, improves our ability to screen for chlamydia.

French

Domaine(s)
  • Méthodes diagnostiques (Médecine)
  • Biochimie
CONT

Ces [...] techniques de laboratoire, en l'occurrence les tests d'amplification des acides nucléiques (TAAN) par la méthode PCR («polymerase chain reaction»), offrent la possibilité de rechercher la chlamydia et la gonorrhée de façon non invasive. [...] On peut effectuer un TAAN sur des sécrétions vaginales provenant du col utérin chez la femme, mais également sur des sécrétions urétrales ou des prélèvements urinaires chez l'homme et la femme.

CONT

Les TAAN sont sensibles et spécifiques et devraient être utilisés dans la mesure du possible avec les échantillons urinaires, urétraux et cervicaux; le sang et le mucus peuvent nuire à la performance du TAAN. Les prélèvements non invasifs comme ceux d'urine peuvent être utilisés pour les TAAN, ce qui facilite l'acceptation des tests par les patients.
