I have a blood test scheduled for elevated ALT liver enzyme on the 9th. I cannot take pain medications. I have come down with a bad cold and am experiencing severe sinus pressure. Can I take Pseudoephedrine, Allegra D, or Mucinex D without affecting my blood test results?

Pseudoephedrine and Mucinex D may affect ALT and liver results. Avoid these 3 to 5 days before your liver test. You can use plain Allegra (non D) after confirming with your doctor. Try steam inhalation, saline nasal spray, and hydration for relief. Repeat LFT, especially ALT, after recovery if needed. Refer to an ENT specialist for further treatment

What does an elevated ALP level indicate?

Answered by Apollo Doctors

My wife, age 32, has UTI with no fever, so we took a routine test. There is slight elevation in conjugated bilirubin. She has no disease of any kind. Why is there an elevation?

My report shows fatty liver infiltration and an umbilical hernia measuring 2.5 x 2.2 cm. I would like to know what the recommended treatment options are and whether this condition is life threatening.
