Hello and thank you for your answers!
If the prescriber did not contact you it means that the result was not a concern. I would tell you that in general, one would be concerned about severe liver disease if other results would be abnormal or if the bilirubin level is above 30.
For the vitamin D supplement, the dose of 10,000u per day is quite high. It would be recommended in cases of significant deficiency or malabsorption (following bariatric surgery for example). I would advise you to take 800 to 1000 units per day or 10 000u per week.
Finally, for your pain, I would advise you to keep a diary of this pain to see when it appears. If it is not too intense, it is less worrying. It would be necessary to consult quickly if the pain prevents you from functioning, if you have difficulty swallowing, if there is red or black blood or bile in the stool or if you lose unwanted weight.
The pain could be related to your stomach, you could go to your pharmacist to try antacid medication to see if it would help.
As I said earlier, I don't feel comfortable reassuring you completely here as I don't have the whole picture and I am not the prescriber for this blood test. If you are concerned about your situation, I encourage you to make an appointment with your doctor to discuss it.
Have a nice day!
Marie-Laurence Gauthier, pharmacist.
