Detailed explanation-1: -Normal clotting time is 14-16 seconds.
Detailed explanation-2: -Minimum and maximum clotting time observed in females is 3minutes 30 seconds and 10 minutes respectively while in males, it is 2 minutes 30 seconds and 5 minutes respsectively. Conclusion Our study suggests that bleeding and clotting time are slightly higher in females.
Detailed explanation-3: -The 20WBCT was first described in 1977 by Warrell and colleagues and involves placing ‘a few millilitres of freshly collected blood into a clean dry glass test tube that is then left un-disturbed for 20-minutes and then tipped to discover whether the blood has clotted’ [4].
Detailed explanation-4: -When the PT is high, it takes longer for the blood to clot (17 seconds, for example). This usually happens because the liver is not making the right amount of blood clotting proteins, so the clotting process takes longer. A high PT usually means that there is serious liver damage or cirrhosis.
