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.

Answer:
Drawing of the structure of compounds showing atoms.
Explanation:
Making structure of the compound is the easiest way to show the atoms present in the compounds or to express chemical formula of the compound because in the structure the atoms from which the compound is formed is clearly shown so draw the structure of the compound is the best and quick way to show the chemical formula of the compound.
Pond organisms live in shallow water so they can produce
Answer:
Pfiesteria species generally found in estuaries, the population of which are needed to be controlled only when they becomes toxic. Presence of large of fish triggers toxicity in Pfiesteria.
Explanation:
Pfiesteria are known to be associated with fish kills as for example large fish kill in the seas of North Carolina. It also causes blooming of algae in enormous numbers thus make the water bodies, hostile for survival of fishes and other marine lives. It affects human too by release of toxins in air and water often resulting in respiratory problems, infections of gastrointestinal system, headaches and fatigue. In this type of grave circumstances, leading to outburst of population of Pfiesteria, there is an urgent need to control.
