what the risks are test, the ability of platelets, a component of blood, to clump together, blood clotting, blood is drawn, a vein, on the inside, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the band to swell, blood, a needle is inserted, vein, blood is collected in an airtight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, an infant, young child, area is cleansed, antiseptic, punctured, a sharp needle, a lancet, blood collected, pipette, small glass tube, on a slide, onto a test strip, into a small container, cotton, a bandage applied, puncture site, any continued bleeding, platelet aggregation test measures the rate, degree to which dispersed platelets, sample of plasma, liquid portion of blood, form clumps, addition of a material that, stimulates aggregation, materials, adp, adenosine diphosphate, epinephrine, arachidonic acid, collagen, ristocetin, clumping of platelets causes, sample to be more clear, less turbid, a machine measures the changes in turbidity, cloudiness, prints a graphic recording, list of medications, affect test results is increasing rapidly, notify health care provider of any medications, over-the-counter preparations, have taken, the preceding 2 weeks, infants, children, test depends on child's age, previous experience, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, the needle is inserted to draw blood, feel moderate pain, others feel only a prick, stinging sensation, some throbbing, this test, often indicated, bleeding tendency qualitatively similar to low-platelet bleeding despite normal platelet count, normal number of platelets, platelets, thrombocytes, small cells, in the bloodstream, the blood clotting process, manufactured, in the bone marrow, bleeding occurs, platelets clump together, site of injury, swell, stick, injured area, a plug to reduce the bleeding, platelet aggregation tests help to diagnose diseases of platelet dysfunction, distinguish between inherited bleeding problems, hemophilia, von willebrand disease, acquired bleeding problems, that occur, another disorder, a side-effect of medication, normal time it takes to cause clumping is temperature dependent, from laboratory to laboratory, the vial is also important, response, different "aggregation stimulators", to distinguish various platelet defects, in particular, difference, the response to ristocetin, products is important, ristocetin triggers aggregation, a different mechanism than the other products, pattern of platelet aggregation, between stimulators, congenital disorders that cause decreased platelet aggregation, glanzmann's thrombasthenia, a rare inherited platelet disorder, platelets fail to aggregate in response to normal stimulation but, clump, in response to ristocetin, bernard-soulier syndrome, a rare inherited disorder, platelets, unable, von willebrand factor, platelets aggregate, in response to most stimulation but, not aggregate in response to ristocetin, response to collagen is blunted, storage pool disease, a group of disorders characterized by defective stimulation by materials, adp, trigger platelet aggregation, - variable abnormalities of platelet aggregation, von willebrand's disease, inherited lack of von willebrand factor, ristocetin cofactor, aggregation, ristocetin, abnormal in type i disease, increased in type ii, acquired conditions that cause decreased platelet aggregation, use of platelet-inhibiting medications, special considerations, autoimmune disorders that produce antibodies against platelets, myeloproliferative disorders, uremia, a result of kidney failure, acquired storage pool disorder, platelets, no longer effective, temporary damage, in response to cardiopulmonary bypass, vasculitis, fibrin degradation products, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, performed, the patient has a bleeding problem, bleeding more of a risk, person than, bleeding problems, medications, test results, aspirin, aspirin compounds, nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, antihistamines, antibiotics, veins, arteries vary in size, obtaining a blood sample.
