Leukocytes in Urine (No Nitrates)

Even in healthy persons, the body is continually fighting pathogens that try to invade it. This battle results damage of some white blood cells. The dead cells are mostly eliminated through urine. That explains why regular urinal discharge has traces of leukocytes.

It however becomes abnormal when the white blood cell count in urine goes past some extent. While not necessarily, the latter situation may indicate various problems in a person’s system.

Leukocytes will increase in numbers inside a problematic urinal tract. The body may either intently deposit them here to help in fighting an infection, or may do so mistakenly when there is a problem with filtration of blood, especially during kidney failure.

If you ever experience strange feelings whenever you pee, it would be a good idea to go for urine test. Certain things like change in urine color, itching, pain in the waist region, frequent visits to the toilet, small amounts of discharge, and low pressure urine release can indicate existence of urinal tract infection (UTI). Parents should watch their children for any of these signs and respond early to them.

Test for leukocytes in urine

There are two initial tests usually done together on urine to confirm first if there is a problem in the urinal tract, and second, what is causing the problem. These are the nitrite test and Leukocyte esterase test. While commercial DIY urine test kits are available for individual home use, it is not advisable to rely entirely on their results, though they can also offer hints about your internal health. The best way to confirm that you are not having any problem is to have a qualified medical practitioner examine you.

Leuckocytes produce an enzyme called esterase that can be detected when a test strip is dipped into urine overcrowded by these cells. This may give hints about presence of a disease.

Afterwards, the person will undergo nitrite test; bacteria infested urine has a lower levels of nitrate or none at all, because pathogens convert this chemical to nitrite, which changes the color of the special strip dipped in it.

Upon confirmation of “Leuckocytes in Urine No Nitrate results”, the patient will need to start on treatment.

Stronger antibiotics are necessary for gram-negative bacteria as compared to those that are needed to kill gram-positive bacteria. Before beginning treatment, the doctor should recommend further microscopic tests to confirm the bacteria type in order to recommend the most appropriate treatment; giving a too strong or too weak treatment to a pathogen might lead to drug resistance.

On the other hand, when there are no nitrites, it may indicate other forms of damage. If the person has had accidents or has been hit in the groin recently, damages might be present in their organs, and these may be responsible for the existence of too many leucocytes in urine. Quick redress is necessary to avoid further relapse.

Other possible causes of leukocytes in urine

Apart from bacterial infections and mechanical damage, other factors may cause leukocytes in urine. They include the following:



Pregnancy may lead to more than normal increase in urine’s white blood cell concentration. This is acceptable to some level due to the increased pressure from the womb as more space opens up for the fetus.

However, it is still very crucial for pregnant mums to go for urine and amnion tests regularly. This group is highly susceptible to vaginal infections that may travel upwards and result in stillbirth or brain damage to the baby.


High blood pressure

Hypertensive people may also have increased white cells in their urine. The pressure within blood vessels may cause their walls to open up to channels around them. Proper medical attention will help to mitigate this.


Kidney stones

Kidney stones occur when minerals and bacteria accumulates in ducts within the kidneys and form hard, stone- like granules, which block the channels and cause pressure on their walls. This can result in excruciating pain and possible kidney failure if not addressed on time. Depending on the level and type of bacterial infection, either Leukocytes in Urine No Nitrate, or nitrate positive results may show after relevant tests.



Certain medications increase permeability of filtration sites. This may cause passage of blood cells into urine, thereby increasing their concentration in the discharge.


Other Symptoms accompanying leukocytes in urine

Apart from pain and itchiness in the urinal tract, persons releasing excess leukocytes may also feel exhaustion and dizziness. A few people have also experienced aura. This is most likely because of an impending illness. Instead of waiting for to be bedridden, the person should seek early treatment.

In addition, excessive loss of leukocytes in itself is damaging to the body. It can compromise a person’s immune system when the body’s white cell production does not match up to what it loses.
