В новой линии пробирок для разделения крови сочетаются качество анализа на сыворотку и скорость анализа плазмы крови.
Greiner Bio-One (Кремсмюнстер, Австрия) представила пробирку Vacuette Serum Fast Tube, проведение анализа в которой с учетом времени на коагуляцию составляет всего пять минут, что позволяет исследовать сыворотку так же быстро, как плазму.
Внутренняя поверхность пробирки Vacuette покрыта активатором свертывания – смесью с добавлением тромбина, которая ускоряет процесс коагуляции. При использовании Vacuette Serum Fast Tube общее время обработки составляет всего 10 минут (коагуляция + центрифугирование), по сравнению с 40 минутами при использовании обычных пробирок для сыворотки, что позволяет легко и эффективно улучшать время обработки.
Пробирка также содержит гель, который образует устойчивый барьер между сывороткой и клеточными компонентами цельной крови после центрифугирования (5 минут при 3000 x g или 10 минут при 1800 x g при 20 градусах Цельсия).
Пробирки Vacuette Serum Fast Tubes изготовлены из герметичного ПЭТ (полиэтилентерефталата), который защищает от контаминации. Пробирки созданы с использованием надежной вакуумной технологии и имеют просто открываемую защитную крышку. Это способствует поддержанию гигиены в рабочих процедурах без риска возникновения брызг, которые могут появляться при использовании стандартных резиновых пробок.
“Благодаря быстрому времени обработки пробирки для исследования плазмы крови все еще остаются популярными. Однако определение некоторых параметров на основе плазмы не подходит для ряда тестов, — сказал Дитмар Лейхтфрид, руководитель группы исследований и разработки/преаналитики в Greiner Bio-One. — В некоторых случаях при применении пробирки для плазмы могут иметь место неверные значения по причине наличия антикоагулянтов или фибриногена. Поэтому зачастую использование сыворотки необходимо.
