Editing Transient ischemic attack (section)

===Laboratory workup===
Laboratory tests should focus on ruling out metabolic conditions that may mimic TIA (e.g. [[hypoglycemia]]), in addition to further evaluating a patient's risk factors for ischemic events. All patients should receive a complete blood count with platelet count, blood glucose, basic metabolic panel, [[prothrombin time|prothrombin time/international normalized ratio]], and [[activated partial thromboplastin time]] as part of their initial workup.<ref name=":7">{{cite journal | vauthors = Adams HP, del Zoppo G, Alberts MJ, Bhatt DL, Brass L, Furlan A, Grubb RL, Higashida RT, Jauch EC, Kidwell C, Lyden PD, Morgenstern LB, Qureshi AI, Rosenwasser RH, Scott PA, Wijdicks EF | display-authors = 6 | title = Guidelines for the early management of adults with ischemic stroke: a guideline from the American Heart Association/American Stroke Association Stroke Council, Clinical Cardiology Council, Cardiovascular Radiology and Intervention Council, and the Atherosclerotic Peripheral Vascular Disease and Quality of Care Outcomes in Research Interdisciplinary Working Groups: the American Academy of Neurology affirms the value of this guideline as an educational tool for neurologists | journal = Stroke | volume = 38 | issue = 5 | pages = 1655–1711 | date = May 2007 | pmid = 17431204 | doi = 10.1161/STROKEAHA.107.181486 | author19 = Clinical Cardiology Council | author18 = American Stroke Association Stroke Council | author17 = American Heart Association | author21 = Atherosclerotic Peripheral Vascular Disease and Quality of Care Outcomes in Research Interdisciplinary Working Groups | author20 = Cardiovascular Radiology and Intervention Council | doi-access =  }}</ref> These tests help with screening for bleeding or [[Hypercoagulability|hypercoagulable]] conditions.
