Leukocyte esterase urine test
May 10, · The presence of WBC esterase trace in urine is a result of urinary tract infection. WBC esterase 1 or Leukocyte esterase 1 is a by-product of WBC. Usually normal: Leukocyte esterase released by lysed neutrophils and macrophages is a surrogate marker of the presence of white blood cells (WBCs). Leukocyte esterase suggests that there are white blood cells in the urine. Trace means few WBC produced small amount of leucocyte esterase .

Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white . Aug 04, · The WBC esterase test specifically looks for signs of infection, such as white blood cells, in urine. If a dipstick color change occurs, the urine sample undergoes microscopic examination to double-check results.
White blood cells WBCs are also called as leukocytes. They protect the body from infections by fighting foreign invaders such as viruses, bacteria, fungi, or parasites. Phagocytes and lymphocytes are forms of white blood cells WBCs. Phagocytes engulf foreign particles like bacteria. Lymphocytes recognize the foreign particles based on previous encounters.
Lymphocytes make up the adaptive immunity of our body. They also produce antibodies that bind to foreign particles, so that they can be recognized for destruction. Since leukocytes help fight off diseases and infections, high levels of leukocytes in urine may indicate an infection or inflammation in the bladder or kidney. It means the body is trying to fight off an infection in the urinary tract.
It could also indicate damage to the ureters, bladder, and urethra. It could also indicate a kidney stone. A high leukocyte count in urine could also indicate hypertension , diabetes , or other kidney diseases. A consistent high leukocyte count in urine can negatively affect the kidneys or bladder. Excess leukocytes that have been killed or damaged while fighting off an infection are expelled by the body through urination. For this reason, the presence of leukocytes in urine does not always mean an infection.
In females, the size of their urethra is smaller compared to males, which is why more leukocytes are found in the urine of females than males. Pregnant women also tend to show leukocytes in urine. During pregnancy, leukocyte counts can suddenly shoot up in urine. One reason may be due to a contamination in the vagina. Other reasons may be an increased level of protein excreted in the urine and bladder infection.
It is advisable to consult a gynecologist, if leukocytes are frequently reported in a routine urinalysis. Kidney problems can cause an increased number of leukocytes in urine. The infection starts in the urinary tract and spreads to the kidney. Such infection is called as pyelonephritis, which can affect any part of the renal system. It can affect the urinary bladder, urethra, and ureter.
People with an impaired immune system and those who use urinary catheters are at a higher risk of developing pyelonephritis. Kidney stones are also proven dangerous since the stones contain calcium salts, which can interfere with the urine pathway in the urethra.
The obstruction can lead to a bacterial infection and presence of leukocytes in urine. Having sex enables the migration of bacteria to the urinary tract, thereby increasing the leukocyte count in the urine. In most cases, when the bladder is full, there is an urge to urinate to empty the bladder. In some cases, when urine is not completely released or when there is delayed urination, the urine left in the bladder acts as a good media for bacteria to thrive on.
This would then cause the bladder to be infected with bacteria leading to an increase in the number of leukocytes in urine. The most common causes of urinary tract obstruction are kidney stones, prostatic hypertrophy, and pelvic trauma.
Due to this blockage, the urinary system is damaged, thereby causing leukocytes to appear in the urine. At times, one may also notice blood in the urine. Interstitial cystitis is also called as bladder pain syndrome. It causes bladder pressure and pain, as well as excessive urination leading to urinary tract infection and an increased leukocyte count in the urine.
Hematuria or blood in the urine and a foul—smelling or cloudy urine may also be present. A urine sample is usually tested for white blood cells or leukocytes, red blood cells RBCs , bacteria, and other substances. When the urine is positive for bacteria, a urine culture is performed to identify the type of bacterial infection.
This is the initial step in diagnosing urinary tract infections UTIs. A microscopic examination is done to look for pyuria pus in urine and hematuria blood in urine. Pyuria is usually present in most women with UTI and in some with urethritis. A midstream clean catch urine is examined to assess pyuria. Urinalysis is the most accurate way for diagnosing bacteriuria bacteria in urine in symptomatic women.
The presence of bacteria in urine is not considered as a single criterion for the diagnosis of UTI. The three acceptable methods for urine collection are midstream clean catch, catheterization, and suprapubic aspiration. Ten or more leukocytes per cubic milliliter in urine is considered as abnormal.
Women with UTI have more than the normal count of leukocytes per cubic milliliter. A Gram stain of urine smears is also a rapid, inexpensive, and accurate method of identifying bacteria in urine. However, a low bacterial count in the lower urinary tract may be associated with a negative Gram stain. White cell casts are strong evidence of pyelonephritis. However, its absence does not rule out an upper urinary tract infection. In the absence of infection, white blood cells can also be seen in renal diseases.
A dipstick test is done to detect leukocyte esterase or nitrite reductase in the urine. It is a commonly used test. Leukocyte esterase is an enzyme produced by the leukocytes. This test detects the presence of leukocytes and other abnormalities associated with infection. The presence of leukocyte esterase indicates pyuria while nitrite indicates bacteriuria.
A positive dipstick test should be considered as a positive screen but a negative test result does not exclude the diagnosis of UTI in a patient with a high risk of infection. Note: This method may show a false positive result in cases of a Trichomonas infection, vaginal secretions, high levels of protein, and a high level of vitamin C in the urine.
Dipsticks can pick up certain substances such as leukocyte esterase and nitrite in the urine. Both of these substances are indicators of infection. If the urine is tested positive for nitrite, it indicates a bacterial infection, although it does not pick up all the bacteria present in the urine. If the urine tests negative for leukocyte esterase, it means an infection is highly unlikely.
If the leukocyte esterase test is positive and nitrite is negative, it can still mean an infection. Such cases can be attributed to poor hygiene or incorrect technique used while collecting the urine sample. It can lead to false results such as the presence of bacteria in the urine without them being actually present in the urinary tract.
To avoid a false positive result, the area around the urethral opening should be rinsed with clean water before collecting the sample. Men should hold back the foreskin and women should hold the genital labia aside. Urine should be collected halfway since the initial amount of urine may be contaminated. Most doctors would prescribe antibiotics for UTI treatment. Doctors may recommend a longer course of antibiotics in case of frequent UTIs.
In the case of a severe kidney infection , it is necessary to closely monitor the patient, or else the condition might become life-threatening. Tumor or kidney stones can be removed through surgery. Surgery is usually required when larger stones are involved. The stones are broken up using sound waves. Treatment options for tumors may include surgery, radiation, or chemotherapy.
Small kidney stones can be flushed out of the system by increasing the amount of water intake. An increased fluid intake can also help flush the bacteria present in the urinary tract. At least two liters of water should be taken a daily. A natural approach is always the best.
The following are some of the natural ways to relieve urinary tract infections:. Research has shown that cranberry is an antibiotic alternative. It can help in the treatment and prevention of UTIs. The hippuric acid present in cranberries is said to have an antibacterial effect against bladder infections. Cranberry extracts can also lower down calcium levels in cases of kidney stones. However, a review of the scientific evidence confirms that cranberry may not be very effective in the form of juice for reducing the occurrence of UTIs.
Hence, it is not actively recommended by doctors. The arbutin content of the berry is converted to an antibacterial compound called hydroquinone, which has been used for centuries to treat UTIs. It cleanses the urinary tract, fights infections, and treats kidney stones. However, it has been found that hydroquinone can potentially damage the liver.
Thus, consult the doctor first before taking it. A high-oxalate diet is thought to be responsible for having frequent kidney stones. Examples of foods that are high in oxalate are spinach, Swiss chard, okra, dried figs, peanuts, almonds, and sesame seeds.
Low-oxalate foods include onions, zucchini, avocado, lime, cherries, coconut, ginger, beef, chicken, and eggs. Goldenseal is an herbal antimicrobial remedy. The active ingredient in goldenseal is berberine. However, further research is needed to prove its potential for treating UTIs.
