How To Diagnose And Treat Liver Cysts

Blood Tests

Blood tests help doctors measure liver function, and they provide additional diagnostic clues about potential cancers and other liver issues. For example, some liver cysts are caused by a parasite known as echinococcus, which is primarily carried by sheep, and a blood test is necessary to detect it. Blood tests can be performed by nurses, phlebotomists, and other medical professionals. Patients who are afraid of needles may wish to use a prescription numbing cream prior to having this test. To take a blood sample, the healthcare professional places a tourniquet around the patient's upper arm and cleans their skin with an alcohol swab. Next, they insert a needle into a vein, normally one near the crease of the elbow. After enough blood has been collected, the needle is removed, and a bandage is placed over the site. Patients who are nervous before the procedure might wish to lie down during their test to reduce the risk of fainting. Blood test results are normally available within a week, and patients will be called if there are any abnormalities.
