Confirm the patient
Use the required identification process and confirm why the urine sample is needed.
Learn how urine dipstick testing is used in clinical practice, how to prepare and test a urine sample correctly, document findings and recognise when an unexpected result requires further assessment.
Urinalysis is the examination of urine to identify characteristics that may contribute useful information about a patient's condition. In many clinical settings, a reagent strip or urine dipstick is used as an initial bedside test.
Dipstick results can indicate the presence of substances such as blood, protein, glucose, ketones, nitrite or leukocytes. However, a positive result does not automatically establish a diagnosis.
Results need to be interpreted alongside the patient's symptoms, medical history, observations and the reason the test was requested.
The usefulness of urinalysis depends heavily on obtaining and handling the specimen correctly.
Use the required identification process and confirm why the urine sample is needed.
Explain how the sample should be obtained and provide privacy and appropriate assistance.
Follow local guidance regarding the specimen container and collection method.
Good collection technique helps reduce contamination that could make the result difficult to interpret.
Confirm that dipsticks are in date, stored correctly and suitable for the testing system used locally.
Follow standard infection-control precautions and use PPE according to the anticipated exposure risk.
Always follow the manufacturer's instructions, local policy and the procedure used by your placement organisation.
Confirm the sample belongs to the correct patient and prepare the approved test strips, timer and documentation.
Follow local and manufacturer guidance to ensure the sample is suitable for testing before applying the strip.
Ensure the required reagent areas contact the urine without unnecessary prolonged immersion.
Handle the strip according to manufacturer guidance so excess urine does not interfere with neighbouring reagent pads.
Compare the reagent pads with the manufacturer's reference chart at the specified times.
Document findings promptly and report unexpected results in the context of the patient's clinical condition.
The exact parameters vary between products. These are common examples and should always be interpreted according to local guidance.
| Dipstick finding | What it may indicate | What a student nurse should remember |
|---|---|---|
| Blood | May be associated with several urinary or non-urinary causes. | Consider symptoms, history and possible sample contamination; report unexpected findings. |
| Protein | May be clinically relevant in a range of conditions. | Do not diagnose from the dipstick alone; document and escalate as required. |
| Glucose | Can occur when glucose is present in the urine. | Consider diabetic history, blood glucose and the wider clinical picture. |
| Ketones | May occur during fasting, illness or altered glucose metabolism. | Ketones alongside significant hyperglycaemia or illness may need urgent assessment. |
| Nitrite | May support suspicion of certain urinary bacteria. | A negative result does not exclude infection and a positive result does not diagnose one alone. |
| Leukocytes | May indicate white blood cells in the urine. | Interpret with symptoms and other findings rather than treating the strip as a diagnosis. |
Urinary symptoms, patient characteristics, clinical assessment and local diagnostic guidance all matter when possible urinary infection is considered.
The urgency depends on the result, symptoms and the patient's overall condition.
Seek prompt review if urinalysis findings occur alongside significant illness, worsening observations, severe pain, reduced consciousness, suspected sepsis, significant hyperglycaemia with ketones or other concerning clinical signs. Follow local escalation procedures.
Accurate documentation helps the wider team understand why testing was performed and what was found.
Record when the specimen was tested and follow local documentation requirements.
Document each required parameter accurately rather than recording only that the urine was βpositiveβ.
Record relevant clinical symptoms or concerns where appropriate.
Record whether a specimen has been sent for laboratory testing as required.
Document who was informed and any further assessment or instructions.
Include relevant information that helps explain why the result matters.
Urinalysis becomes much easier when you understand what the test can and cannot tell you.
