Screening, or buffing, the floor will only remove light marks caused by normal wear and tear. Once the floor is screened (lightly sanded) it will be coated with a coat of polyurethane. It usually takes one day to screen and recoat a hardwood floor. Screening will not remove deeper scratches and indentations.
Definition. A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. Liver biopsies are sometimes called percutaneous liver biopsies, because the tissue sample is obtained by going through the patient's skin.
A liver biopsy can show how much iron is in your liver. This procedure also can help your doctor diagnose liver damage (for example, scarring and cancer). Liver biopsies are less common now than in the past.
