[Warning: The following story contains spoilers about Wednesday's episode of Criminal Minds. Read at your own risk.] That sound you hear is baby girls crying everywhere. After 11 years and (probably) 103 broken doors and 214 tackles, Shemar Moore exited Criminal Minds on Wednesday's episode.
A prothrombin time (PT) is a test used to help detect and diagnose a bleeding disorder or excessive clotting disorder; the international normalized ratio (INR) is calculated from a PT result and is used to monitor how well the blood-thinning medication (anticoagulant) warfarin (CoumadinÂ®) is working to prevent blood clots.
International Normalized Ratio Blood Test-INR Normal INR Values: 1 to 2 The INR is used to make sure the results from a PT test is the same at one lab as it is at another lab. In the 1980s the World Health Organization determined that patients may be at risk because the results of a PT test would vary from one lab to another, based upon the way the test was done.
