The Opelousas Trail through Angelina County. The name of the trail and the route outside Angelina County is somewhat confused. Some say it was called the Beef Road (or Trail), but the Texas Highway Department map shown above calls it the Opelousas Trail.
The normal range for serum creatinine (in the blood) is usually between 0.6 and 1.3 milligrams per deciliter (mg/dL) although it varies between labs, between men and women, and by age.
In many labs the normal range is 0.6 to 1.2 mg/dl. Higher levels may be a sign that the kidneys are not working properly. As kidney disease progresses, the level of creatinine in the blood increases.
