1 Nobody else can buy the property during the lease option period. 2  If the Buyer does not exercise the lease option and purchase the property at the end of the lease option, the option expires.  The Buyer is not obligated to buy the property.
INR = [PTpatient Ã· MNPT]ISI. The INR has no units (it is a ratio) and is determined to one decimal place. The first step of the INR calculation is to ânormalizeâ the PT by comparing it to the mean normal prothrombin time (MNPT), the geometric mean of the prothrombin times of the healthy adult population. In the second step, this ratio is raised to a power designated the ISI, or international sensitivity index.
By entering a PT result into a math formula, it yields the INR. The international normalized ratio means one labâs test results can be compared to anotherâs with high accuracy. A normal INR is approximately 1.0. People taking the blood thinner warfarin typically have a target INR of 2.0 to 3.0.People with an INR higher than the normal range who arenât taking warfarin may have a medical condition that needs further evaluation.A low INR is rarely significant. normal INR is approximately 1.0.
