Phosphate in Blood

Blood Phosphate (PO4), PO4 (Phosphate), Blood

What Affects the Test

Results from a blood phosphate test may be affected by:

• Drinking alcohol before the test.
• Using some medicines that can increase phosphate levels, such as androgen hormones, anabolic steroids, and enemas that contain phosphate.
• Taking too much vitamin D.
• Using some medicines that can decrease phosphate levels, such as antacids, insulin, acetazolamide, and epinephrine. A large infusion of sugar (glucose) that causes insulin levels to increase can also decrease phosphate levels.
• Having a disease, such as lymphoma, that causes calcium levels to rise or fall.
• Having a rare disease, such as diabetes insipidus, that causes the kidneys to produce large amounts of urine.
