The dipstick test is a urine test that can be bought over the counter and should be taken in the morning when the urine is highly concentrated, notes WebMD. Collect the urine in a glass container so you can clearly view the urine and check for traces of blood. Dip the dipstick in the urine, observe the color change of the stick, and compare it to the given chart. The chart shows the color changes expected for a range of blood concentrations.
Blood in the urine is often visible and makes the urine appear pink to light brown, and this is called gross hematuria, notes the National Institute of Diabetes and Digestive and Kidney Diseases. Microscopic hematuria means that the blood is not visible and requires a dipstick test.
People who are more at risk of attacks from hematuria are the elderly and people with a family history of kidney disease. In addition, those with enlarged prostates or are on medications such as blood thinners may also suffer from this condition, notes the National Institute of Diabetes and Digestive and Kidney Diseases.
Other dipstick tests also examine the presence of white blood cells or protein traces according to WebMD. The presence of any of these substances may indicate an infection.
