Not sure if this has been brought up in the last five pages, but that is a liver function test and a profile. For diagnosing any form of leukemia, it's not relevant. The only two pieces of data that aren't normal in that mess are triglycerides and low high density lipoproteins. Basically, the patient that came from has higher than normal fat in their blood and low good cholesterol. That describes pretty much everyone in America.
If you sent a blood sample to the lab for that report, all you'd get back is the data from the lab. The lab doing a liver function test would not report back on suspected or confirmed leukemia because that's not the test they've been asked to run. If I send a lab a request to give me (insert lab here) test, they send back what they're asked for and no more.
Also, a physician does not diagnose "leukemia." There are a laundry list of different kinds of leukemia, such as Acute Lymphoblastic Leukemia, Chronic Myeloid Leukemia, and Hairy Cell (yes) Leukemia. You would ideally want a description of a biopsy and a complete blood count (tells you what cells and how many are in the blood). You wouldn't casually append it to a list of liver tests with no details.
I'd also add that "Leukemia POS" is in a different font with all the footnotes at the bottom referring to the tests described above. No leukemia is abbreviated POS that I know of: it's usually AML, ALL, CML, CLL, and a few oddball types, but none of them are labeled POS. I'd go with POS standing for "Piece of Shit."
TL;DR: It's almost certainly a very clumsy fake.
