The D-xylose absorption test can make a person nervous since it involves the extraction of blood and the sampling of urine. However, there is very little possibility of a severe issue from getting a blood sample collected from a venous blood vessel.
Effects of D-xylose Absorption Blood Tests
A person could get a minor bruise at the puncture site. However, one could lessen the risk of bruising by maintaining pressure on the puncture site for a few minutes. In certain cases, the vein may turn swollen once the blood sample is collected. This problem is known as phlebitis. A hot compress could be applied a few times a day to address this.
Persistent bleeding after a D-xylose absorption tests could mean trouble for patients with bleeding problems. Aspirin, Coumadin (warfarin), and other heart disease drugs could make bleeding more imminent. If you have bleeding or coagulation issues, or if you take heart disease medications, tell your physician prior to having blood samples collected.
Effects of D-xylose Absorption Urine Tests
This particular procedure could cause dehydration problems. Make sure that you consume enough water to replace diminished liquids after you've completed the exam.
Consuming the D-xylose solution could bring about vomiting, nausea, or looseness of the bowels. Tell your physician if you experience issues after consuming the D-xylose preparation.
Results of D-xylose Absorption Tests
Bloodstream levels of D-xylose are greatest approximately two hours after consuming the D-xylose preparation. Almost all of the D-xylose is passed from the system in the urine within five hours. If the bowels cannot absorb the D-xylose the right way, the level of D-xylose in the urine and blood will be extremely low.
Several illnesses can alter D-xylose amounts. Your physician can talk about any significant irregular results with you in reference to your signs and symptoms and past wellness.
Abnormally high values in D-xylose absorption tests can be induced by either a condition, such as Hodgkin's disease, dermatosclerosis, or radiation therapy.
Things that may interfere with the final test results or the accuracy of your final results include:
- Large amounts of microbes (bacteria) in the bowels.
- Renal disorder or bladder issues that keep you from wholly emptying your bladder.
- Drugs, like antibiotics, aspirin, and heart medications. Many drugs could impact D-xylose exam results.
- Physical activity during the examination. You'll be recommended to relax quietly until the exam is all over.
- Illnesses that make food stay in the GI tract for a long period.
To conclude, make sure you consume enough water to replace lost liquids once you have finished the test. Tell your physician if you experience diarrhea after consuming the D-xylose preparation.
