You shouldn't be getting a positive on your FOBT. But it could be something relatively minor. You obviously need to follow up with your doctor. Here's more info on what your results mean from online sources -
Creatinine: I'm not sure what units your results are in.
"Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dl) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. (In the metric system, a milligram is a unit of weight equal to one-thousandth of a gram, and a deciliter is a unit of volume equal to one-tenth of a liter.)
Muscular young or middle-aged adults may have more creatinine in their blood than the norm for the general population. Elderly persons, on the other hand, may have less creatinine in their blood than the norm. Infants have normal levels of about 0.2 or more, depending on their muscle development. In people with malnutrition, severe weight loss, and long standing illnesses the muscle mass tends to diminish over time and, therefore, their creatinine level may be lower than expected for their age.
A person with only one kidney may have a normal level of about 1.8 or 1.9. Creatinine levels that reach 2.0 or more in babies and 10.0 or more in adults may indicate severe kidney impairment and the need for a dialysis machine to remove wastes from the blood. "
"The normal range for WBC count is 4,300 to 10,800 cells per cubic millimeter (cmm) or 4.3 to 10.8 x 109 cells per liter. A range of 11 to 17 x 109/L may be considered mild to moderate leukocytosis, and a range of 3.0 to 5.0x109/L may be considered mild leukopenia."
"The general the range is as follows:
Male: 4.7 to 6.1 million cells per microliter (cells/mcL)
Female: 4.2 to 5.4 million cells/mcL
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results."
FOBT - "The FOBT test is normally negative. A positive test result will tell your doctor that you have abnormal bleeding occurring somewhere in your gastrointestinal tract. This blood loss could be due to ulcers, diverticulosis, bleeding polyps, inflammatory bowel disease, hemorrhoids, from swallowed blood due to bleeding gums or nosebleeds, or it could be due to benign or cancerous tumors. Anything that protrudes into the lumen (the empty space in the intestine), like a polyp or tumor, and is rubbed against by the fecal waste as it passes through has the potential to eventually bleed intermittently. Often, this small amount of blood is the first, and sometimes the only, sign of early colon cancer, making the FOBT a valuable screening tool."
Here's a quick summary of what urinalysis detects from medicinenet.com:
"What kind of cells can be detected?
Epithelial (flat cells) and red and white blood cells may be seen in the urine.
Sometimes cells, cellular debris, and casts are seen in the microscopic urinalysis. Epithelial cells (cells in the lining of the bladder or urethra) may suggest inflammation within the bladder, but they also may originate form the skin and could be contamination.
Casts and cellular debris originate from higher up in the urinary tract, such as in the kidneys. These are material shed from kidney cell lining due to injury or inflammation and travel down through the urinary tubes. These usually suggest an injury to the kidney from an inflammation or lack of blood flow to the kidneys. Rarely, tumor cells can be in the urine suggesting a urinary tract cancer.
What can the presence of red blood cells in the urine mean?
Red blood cells can enter the urine from the vagina in menstruation or from the trauma of bladder catheterization.
A high count of red blood cells in the urine can indicate infection, trauma, tumors, or kidney stones. If red blood cells seen under microscopy look distorted, they suggest kidney as the possible source and may arise due to kidney inflammation (glomerulonephritis). Small amounts of red blood cells in the urine are sometimes seen young healthy people and usually are not indicative of any disease.
What can the presence of white blood cells in the urine mean?
Urine is a generally thought of as a sterile body fluid, therefore, evidence of white blood cells or bacteria in the urine is considered abnormal and may suggest a urinary tract infection such as, bladder infection (cystitis), infection of kidney (pyelonephritis). White blood cells may be detected in the urine through a microscopic examination (pyuria or leukocytes in the blood). They can be seen under high power field and the number of cells are recorded (quantitative).
White cells from the vagina or the opening of the urethra (in males, too) can contaminate a urine sample. Such contamination aside, the presence of abnormal numbers of white blood cells in the urine is significant. "
I'm assuming your doctor would want to see you urgently if they thought the results required a follow up.
