Coagulation , also known as clotting , is the process by which blood changes from a liquid to a gel , forming a blood clot. It potentially results in hemostasis , the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion and aggregation of platelets , as well as deposition and maturation of fibrin. Coagulation begins almost instantly after an injury to the endothelium lining a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial tissue factor to plasma factor VII , which ultimately leads to cross-linked fibrin formation. Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: additional coagulation clotting factors beyond factor VII listed below respond in a cascade to form fibrin strands, which strengthen the platelet plug.
Welcome to Practical-Haemostasis. It stems from a series of seminars that have run in Cambridge for some years and covers many of the commonly used and less commonly used laboratory tests and their interpretation. Screening Tests. Comments How to find your way around: The Site Map will show you what tests are currently available and is a quick way to move around the site. Some older, rarely performed tests may not have a unique page allocated to them but they will still be covered in the site.

Metrics details. Ensuring quality has become a daily requirement in laboratories. In haemostasis, even more than in other disciplines of biology, quality is determined by a pre-analytical step that encompasses all procedures, starting with the formulation of the medical question, and includes patient preparation, sample collection, handling, transportation, processing, and storage until time of analysis. This step, based on a variety of manual activities, is the most vulnerable part of the total testing process and is a major component of the reliability and validity of results in haemostasis and constitutes the most important source of erroneous or un-interpretable results. Pre-analytical errors may occur throughout the testing process and arise from unsuitable, inappropriate or wrongly handled procedures. Problems may arise during the collection of blood specimens such as misidentification of the sample, use of inadequate devices or needles, incorrect order of draw, prolonged tourniquet placing, unsuccessful attempts to locate the vein, incorrect use of additive tubes, collection of unsuitable samples for quality or quantity, inappropriate mixing of a sample, etc. Some factors can alter the result of a sample constituent after collection during transportation, preparation and storage.

Обменные операции явно не относились к числу сильных сторон Двухцветного: сто песет составляли всего восемьдесят семь центов. - Договорились, - сказал Беккер и поставил бутылку на стол. Панк наконец позволил себе улыбнуться.
Мне был нужен человек, никак не связанный с государственной службой. Если бы я действовал по обычным каналам и кто-то узнал… - И Дэвид Беккер единственный, кто не связан с государственной службой. - Разумеется, не единственный.
А на этот рейс были свободные места. - Сколько угодно, - улыбнулась женщина. - Самолет улетел почти пустой.
Вырубить электропитание и снова его включить значило лишь вызвать повторное замыкание. Труп надо передвинуть. Стратмор медленно приближался к застывшему в гротескной лозе телу, не сводя с него глаз. Он схватил убитого за запястье; кожа была похожа на обгоревший пенопласт, тело полностью обезвожено. Коммандер зажмурился, сильнее сжал запястье и потянул. Труп сдвинулся на несколько сантиметров.
