Pre-Op testing (deciphering codes)

I got my paperwork from the surgeon and I have several tests I need done but I'm not sure what they are or what to expect, I'm hoping someone can help me decipher these! U/A (urine analysis?) CBC (I think this is a complete blood count?) PT PTT SMAT 18 EKG - is this where they make you ride a bike and measure your heart rate? and the Chest X-ray which I've already had done. Any help would be appreciated, I'm just wondering what some of those tests are and what they determine. Thanks!!!!!

PT and PTT are to test blood clotting I believe. I don't know about the SMAT 18 though. When I was taught to do a EKG, we didn't do a bike, just hooked up the person and recorded. U/A and CBC I do believe you are correct...but I not even in nursing school 1 more semster left before I apply. Tracey

SMAT 18 is just a general chemistry panel that tests glucose, potassium, sodium, bilirubin, etc.

PT = Prothrombin Time PTT = Partial Thromboplastin Time Both are coagulation tests to see how thin your blood is and if you will stop bleeding in a reasonable amount of time during surgery and/or if you might be prone to PEs. CBC = Complete Blood Count (you were right) and includes RBC (Red blood count) | HGB (Hemoglobin) | HCT (Hematocrit) | MCV (Mean Corpuscular Volume) | MCH (Mean Corpuscular Hemoglobin) | MCHC (Mean Corpuscular Hemoglobin Concentration) | RDW (Red Cell Distribution Width) | Platelets | MPV (Mean Platelet Volume) | WBC - Neutrophils | Lymphocytes | Monocytes | Eosinophils | Basophils Jan

That is all "Greek" to me. Pre-op I had lung xray, upper GI, sonagram, they tested the blood gases and did a breathing test. On the sonagram they looked at my gallbladder and kidneys. They found a gallstone so the gallbladder came out at surgery too. Before surgery I had a complete physical with my heart dr as I wanted to make sure everything was ok there before surgery. I told someone I was was checked from top to bottom prior to surgery, some required and some for precaution.
