The researchers therefore suggest: ‘In neonates and infants multiple reference samples must define the normal range in coagulation proteins for age group more precisely.’ The group examined blood samples from 218 healthy children aged 1-6 months , 7-12 weeks , 1-5 years , 6-10 years , 11-18 years , and over 19 years using two different analyzers; the Behring Coagulation System and the CA-1500 program . There is good correlation between your two systems for all coagulation markers, except prothrombin and activated partial thromboplastin period.

The next step for future study, he said, is certainly to show that the perfusion abnormalities correlate with specific clinical symptoms. ‘At the moment, we have just dichotomized [patients] into Alzheimer’s and FTD,’ he said. ‘But of training course cognitive impairment is usually more complex – – you have a range of impairments.’ The technique has the potential to distinguish other styles of dementia aswell. Schuff plans to review a more substantial sample in a clinical setting, with the goal of determining whether this is possible.
