My brother-in-law undergone series of test (Ultrasound, since he's complaining that he has stomachaches), Blood test to check his platelet count. Another test is an ANA (Antinuclear Antibody) Test, to check if he has lupus (https://medlineplus.gov/lab-tests/ana-antinuclear-...).

Yesterday he experienced vomiting and bleeding while he's pooping. The doctor told us he's experiencing internal bleeding since his platelet count is low. Doc provided him med that will stop internal bleeding and gave him oxygen to help him rest .

Another test is a peripheral smear which they can check the appearance of RBC, WBC and platelet count.

Right now we're hoping and praying that his condition will improve within the next few days.
