I was recently in a detox center for heroin abuse. I have abused opiates for about 4 years with intermediary periods of sobriety for the last year and a half (6 months sober to 8 months sober and around 4 months sober). I am reading the result of a urine test that I had taken during my time at the detoxification center where my creatinine level was abnormally high, 330.10 mg/dL. I had been abusing heroin for 3 months prior to this treatment center. I was absolutely dehydrated and malnourished during the duration of that 3months. I'm reading everywhere that a reading like that is kidney failure or other very serious conditions. I am 30 years old I have been active my entire life and was involved in rigorous work regiments up untill my opiate abuse at 25. Are there any other causes to having such a high reading of creatinine other then the most severe worst case scenario? I was in very good shape 3 months ago before this run and have lost at least 25 pounds during the 3 months of heroin abuse (mostly muscle mass) and I barely ate anything during the day during this time. Please if any can help me out of greatly appreciate it, I need to know if I should go directly to a doctor now.

Creatinine levels are usually a indicator of renal functions in the body.

There are different types or causes of Kidney diseases. For your information, Systemic Kidney disease usually affects both kidneys. If the kidney's ability to filter the blood is seriously damaged by disease, wastes and excess fluid may build up in the body.

The medical test results need to be assessed along with consideration of your clinical examination findings and other medical issues that you might have. If you are completely in good health with normal blood pressure, then these findings would be nonspecific.

If the WBC & Red cells in urine are in higher range, then they could be sign of urinary infection.

Although many forms of kidney disease do not produce symptoms until late in the course of the disease, there are six warning signs of kidney disease:

1. High blood pressure.

2. Blood and/or protein in the urine.

3. A creatinine and Blood Urea Nitrogen (BUN) blood test, outside the normal range. (BUN and creatinine are waste that build up in your blood when your kidney function is reduced).

4. A glomerular filtration rate (GFR) less than 60. GFR is a measure of kidney function.

5. More frequent urination, particularly at night; difficult or painful urination.

6. Puffiness around eyes, swelling of hands and feet.

Once you consult your doctor, you might be able to get proper information about your condition.

I hope this helps.
