A blood test for glaucoma? That's pretty unusual. Last I heard glaucoma (acute or chronic) is not something you could detect via a blood test - the key criteria for detecting chronic glaucoma are (a) optic disc appearance, (b) visual field testing and (c) eye pressure. Your GP typically can't test these, but they can be tested by your optician, who can refer you to the hospital eye clinic if they suspect glaucoma. Blood tests in the glaucoma clinic are mostly used to rule out optic nerve diseases other than glaucoma if a glaucomatous defect is found with the disc & fields in the presence of normal eye pressure.

Go to the doctor an get a blood test for glaucoma, my grandmother was suspected to have it as well so we were all tested as a precaution.

Anyway, chronic glaucoma doesn't cause an acute red eye, so it's not likely to be the cause of the OP's symptoms.
