Squamous Epithelial Cells in Urine: What It Means

Squamous epithelial cells reported as “/LPF” in urine are a common urinalysis finding and often point to sample contamination rather than disease. Understanding the result in context, along with symptoms and other lab values, helps determine whether any follow-up is needed.

Overview

When a urine test reports squamous epithelial cells per low-power field, often written as “squamous epithelial /LPF,” it is describing what the laboratory saw under the microscope. These are flat cells that usually line the outer skin surface and the lower part of the urinary tract, not the bladder itself. In many cases, their presence in urine simply means that a small amount of material from outside the bladder entered the sample during collection.

This finding is common and is not automatically a sign of illness. For many people, especially those who provided a midstream urine sample quickly or during a busy clinic visit, the result reflects how the specimen was collected rather than what is happening inside the urinary tract. The result becomes more meaningful when it is considered together with symptoms and the rest of the urinalysis.

For international patients arranging care from abroad, it can be helpful to think of this result as one piece of a larger picture. A doctor may review whether the sample was clean-catch, whether there are signs of infection, and whether repeat testing would give a clearer answer before recommending any treatment.

Symptoms

Squamous epithelial cells themselves do not cause symptoms. People usually find out about them only when a urine test is done for another reason, such as urinary burning, routine screening, pregnancy care, or evaluation before a procedure.

If the urine sample is contaminated, the test may be less dependable, but the contamination does not necessarily cause discomfort. Any symptoms a person has are more likely related to the reason the urine test was ordered, such as a urinary tract infection, vaginal irritation, dehydration, or another urinary condition.

Symptoms that may prompt a urine test include:

• Burning or pain when urinating
• Needing to urinate frequently or urgently
• Cloudy or foul-smelling urine
• Pain in the lower abdomen or back
• Blood in the urine
• Fever or chills with urinary symptoms

When symptoms are present, the squamous epithelial cell count is interpreted alongside other findings. A sample with many squamous cells may be less useful for deciding whether an infection is truly present.

Causes & Risk Factors

The most common reason for squamous epithelial cells in urine is contamination during collection. This can happen when cells from the skin, vulva, or outer urethral area enter the specimen cup. It is especially common if the urine is not collected as a midstream clean-catch sample.

Several everyday factors can increase the chance of contamination. These include hurried sample collection, difficulty holding the urine stream, limited access to clean-catch instructions, menstrual blood, vaginal discharge, or collecting the sample without first cleaning the area. Children and people with mobility limitations may also have more difficulty providing a perfectly clean specimen.

Less commonly, epithelial cells may appear in urine because of irritation or shedding somewhere along the urinary tract. A doctor will usually look for other clues before deciding whether this is important. The result alone rarely identifies a specific disease.

Factors that can make squamous epithelial cells more likely on a urine test include:

• Improper clean-catch technique
• Menstruation or vaginal discharge
• Skin or genital contamination of the specimen
• Recent sexual activity before collection
• Difficulty providing a midstream sample
• Inflammation or irritation of nearby tissues

Diagnosis

Squamous epithelial cells are identified during urinalysis, usually as part of a routine microscopic exam of the urine sediment. The laboratory may report the number of cells per low-power field, or /LPF, which gives a rough estimate of how many were seen in each microscope field.

The value is most useful when the clinician compares it with the rest of the report. For example, white blood cells, red blood cells, nitrites, bacteria, protein, or crystals may point toward infection, bleeding, kidney irritation, or another condition. If squamous cells are high but other findings are unclear, the sample may simply be considered contaminated.

Doctors often decide whether to repeat the test based on the overall situation. A repeat specimen collected carefully can help avoid unnecessary antibiotics or further testing. In some cases, especially when symptoms are strong, a urine culture or additional evaluation may still be recommended even if the sample is imperfect.

A clean-catch repeat sample usually involves:

• Cleaning the genital area as instructed
• Starting to urinate into the toilet first
• Collecting the midstream portion in the sterile cup
• Closing the container promptly and delivering it quickly to the lab

Treatment Options

Squamous epithelial cells in urine do not require treatment on their own. The next step depends on why they are present and whether another condition is being evaluated. If the result is due to contamination, the simplest solution is often to repeat the urine test with careful collection instructions.

If the urinalysis suggests a urinary tract infection, treatment is directed at the infection rather than the epithelial cells. If there are signs of another urinary, kidney, or gynecologic issue, the doctor may recommend additional tests, imaging, or referral to a specialist. The exact plan depends on the person’s symptoms, medical history, and the pattern of the Blood Test Results: Causes and Meaning" class="ahp-ilk">test results.

For patients traveling for care, this is one of the reasons doctors may prefer to review the full laboratory report rather than a single line item. A well-planned follow-up can prevent both over-treatment and delays in identifying a real problem.

Prevention & Self-care

While squamous epithelial cells themselves are not a condition to prevent, good urine collection technique can reduce confusing results. Clear instructions before testing are especially helpful for people who have had repeated “contaminated” samples in the past.

General self-care also depends on the larger urinary picture. Drinking enough fluid, avoiding urinary irritants if advised by a doctor, and seeking timely care for urinary symptoms can all help keep the evaluation straightforward. People who are menstruating or have active vaginal discharge may want to tell the clinic before providing a sample, since timing or collection method may affect the result.

Practical steps that may improve urine sample quality include:

• Use a midstream clean-catch method
• Wash hands before collecting the sample
• Follow the clinic’s cleaning instructions closely
• Avoid touching the inside of the container
• Provide the sample promptly after collection
• Tell the clinician about menstruation or discharge if relevant

These steps do not replace medical assessment. They simply make the test more accurate and easier to interpret.

When to See a Doctor

A doctor should review the result if squamous epithelial cells appear together with urinary symptoms, an abnormal urinalysis, or a concern for infection. This is especially important when the person has fever, flank pain, nausea, blood in the urine, or worsening discomfort, since those findings need clinical attention rather than guesswork.

Medical review is also sensible if urine tests keep returning as contaminated, if the person is pregnant, if there is a history of kidney disease, or if there are recurrent urinary symptoms that never fully resolve. In these situations, a more carefully collected specimen or a broader workup may be needed.

For international patients who need coordinated evaluation, a multidisciplinary team can help interpret the urine report in context and plan the next steps efficiently. At Acibadem Health Point, multidisciplinary specialists and JCI-accredited hospitals diagnose and treat urinary conditions for international patients with a coordinated approach.

Seek prompt medical advice if urinary symptoms are accompanied by fever, severe pain, inability to urinate, or visible blood in the urine. These symptoms do not necessarily mean a serious problem, but they do deserve timely assessment.
