If the blood specimen from a dermal puncture is clotted before being mixed with the anticoagulant in the microcollection contain
kakasveta [241]

If the blood specimen from a dermal puncture is clotted before being mixed with the anticoagulant in the micro collection container, it will not be suitable for testing.

<h3>Why clotted blood cannot be used for testing?</h3>

In order to stop the loss of blood from damaged blood arteries, tissues, or organs, blood coagulation is a process where circulating components in the blood system are transformed into a gel with insoluble properties. The body creates a blood clot out of fibrin and platelets (thrombocytes) when a blood vessel (a vein or an artery) is wounded in order to stop further blood loss. Blood clots can still develop in the body even when no blood vessels are damaged. An embolus is a clot or a portion of a clot that separates and starts to move around the body.

Clotting has a negative impact on our automated hematology analyzer and unpredictably invalidates cell counts resulting in errors while testing.

Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.
