I have no idea why my doctor ordered it. I've been dealing with some GI issues, but had a colonoscopy which was normal. So IDK why he ordered it. Kinda freaking me out. I just had an abdominal ultrasound today and that came back normal. My platelet count has been low, so I'm being referred to a hematologist, but my GI doc reassured me that it's only mildly low and it might just be the "normal" for my body. All other blood counts (white blood cell, red blood cell, ect) is normal.
But I just know that if this test comes back elevated I'm automatically going to assume I have some type of cancer (as that is what I tend to gravitate to), because cancer can elevate it as well.
