Eating is generally not recommended before checking coagulation 7 and blood tests.
Clinical hematology tests can be divided into two types, one is a blood biochemistry test including liver and kidney function performed on an empty stomach. The other type does not require fasting and includes routine blood tests and coagulation tests. You can eat before the coagulation test and routine blood test, and it usually does not affect the results. If you eat before the test, it is best to choose a light diet and not overeat to avoid the possibility of celiac disease.
However, current blood test regulations vary from hospital to hospital, and for the sake of rigor of results, some hospitals require fasting before performing all hematology tests. Therefore, although eating will not affect the Coagulation 7 and blood tests, it is recommended to fast in order to successfully complete the blood tests and obtain more accurate results.
