A urinary tract infection (UTI) is an infection that affects part of the urinary tract.[1] When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis).[9] Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder.[1] Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI.[9] Rarely the urine may appear in red colour.[6] In the very old and the very young, symptoms may be vague or non-specific.
The most common cause of infection is Escherichia coli, though other bacteria or fungi may sometimes be the cause.
What is a positive urine culture?
A "positive" or abnormal test is when bacteria or yeast are found in the culture. This likely means that you have a urinary tract infection or bladder infection. Other tests may help your provider know which bacteria or yeast are causing the infection and which antibiotics will best treat it
urine culture is a test to find germs (such as bacteria) in the urine that can cause an infection. Urine in the bladder is normally sterile. This means it does not contain any bacteria or other organisms (such as fungi). But bacteria can enter the urethra and cause a urinary tract infection (UTI).
A sample of urine is added to a substance that promotes the growth of germs. If no germs grow, the culture is negative. If germs grow, the culture is positive. The type of germ may be identified using a microscope or chemical tests. Sometimes other tests are done to find the right medicine for treating the infection. This is called sensitivity testing.
UTIs are more common in women and girls than in men.
The most common cause of infection is Escherichia coli, though other bacteria or fungi may sometimes be the cause.[2] Risk factors include female anatomy, sexual intercourse, diabetes, obesity, and family history.[2] Although sexual intercourse is a risk factor, UTIs are not classified as sexually transmitted infections (STIs).[11] Kidney infection, if it occurs, usually follows a bladder infection but may also result from a blood-borne infection.[12] Diagnosis in young healthy women can be based on symptoms alone.[4] In those with vague symptoms, diagnosis can be difficult because bacteria may be present without there being an infection.[13] In complicated cases or if treatment fails, a urine culture may be useful.[3]
In uncomplicated cases, UTIs are treated with a short course of antibiotics such as nitrofurantoin or trimethoprim/sulfamethoxazole.[6] Resistance to many of the antibiotics used to treat this condition is increasing.[1] In complicated cases, a longer course or intravenous antibiotics may be needed.[6] If symptoms do not improve in two or three days, further diagnostic testing may be needed.[3] Phenazopyridine may help with symptoms.[1] In those who have bacteria or white blood cells in their urine but have no symptoms, antibiotics are generally not needed,[14] although during pregnancy is an exception.[15] In those with frequent infections, a short course of antibiotics may be taken as soon as symptoms begin or long-term antibiotics may be used as a preventive measure.[16]
About 150 million people develop a urinary tract infection in a given year.[2] They are more common in women than men.[6] In women, they are the most common form of bacterial infection.[17] Up to 10% of women have a urinary tract infection in a given year, and half of women have at least one infection at some point in their lifetime.[4][6] They occur most frequently between the ages of 16 and 35 years.[6] Recurrences are common.[6] Urinary tract infections have been described since ancient times with the first documented description in the Ebers Papyrus dated to c. 1550 BC
What can urine culture detect?
A urine culture is a test that can detect bacteria in your urine. This test can find and identify the germs that cause a urinary tract infection (UTI). Bacteria, which typically cause UTIs, can enter the urinary tract through the urethra.
What is the normal range for a urine culture?
For that reason, up to 10,000 colonies of bacteria/ml are considered normal. Greater than 100,000 colonies/ml represents urinary tract infection. For counts between 10,000 and 100,000, the culutre is indeterminate. Sensitivity refers to the antibiotics tested to be effective in stopping the bacteria.
