INR Controls are important, they show us how "runny" the blood is.
In order for Coumadin (Warfarin) to have an effect, it must be at a certain level in the blood (ie, the blood must be diluted at a certain rate). If it is less than the desired range, it will not act and clots will form. If it is too much, bleeding can be seen this time. A blood test is done to adjust the dose that is most effective. The blood test performed is the INR test. INR is a test that measures blood clotting time. Your doctor will adjust the dose of the medicine and what the value of your blood tests should be. The amount of Coumadin (Warfarin) you should take may change over time, so it is necessary to have a blood test and consult your doctor at times recommended by your doctor, and the dose of your Coumadin (Warfarin) medication should be adjusted. While the INR value is usually aimed to be between 2 and 4 under Coumadin (Warfarin) therapy, in some specific cases this value is customized by the treating Doctor, such as 2.5 - 3.5.
The example about the mattress sizing page you mentioned in the last WBF can be a perfect example of new keywords and content, and broadening the funnel as well. I can only imagine the sale numbers if that was the site of a mattress selling company.
