Routine Urine Examination
Accurate and Reliable Urine Analysis for Early Detection of Health Conditions
Introduction to Routine Urine Examination

Procedure (Step-by-Step)
Step 1
Clean genital area with soap and water, followed by a swab.
Step 2
Pass the initial urine into the toilet, then collect a midstream sample (at least 5ml) in a sterile container.

Clinical Pathology
● Urine & Stool Tests: First-morning urine is preferred for pregnancy tests. For occult blood in stool, avoid non-veg, aspirin-like drugs, and hard brushing for 3 days before the test.
● Semen Analysis: Abstain from intercourse for at least 3 days and collect the sample in a sterile container.
● Urine for Microalbuminuria: No preparation needed, random sample accepted.
Pus or Exudate
This should be submitted in a sterile screw-capped bottle. Swabs should be loaded well with the material. Two swabs should preferably be collected, one for microscopy and the other for culture.
Throat Swab
Avoid eating and drinking 1 hour before the sample collection. The patient is asked to protrude the tongue and elevate the uvula. A tongue depressor is used to collect samples from children. The swab is rubbed with a sterile cotton swab with rotation over one tonsillar area, then the arch of the soft palate and uvula, the other tonsillar area and finally the posterior pharynx. The swab should be replaced in its tube.
Fine Needle Aspiration
This should be submitted in a sterile screw-capped bottle. Swabs should be loaded well with the material. Two swabs should preferably be collected, one for microscopy and the other for culture.
LBC
(Liquid Based Cytology)
Sample to be collected in gynaecologist office or at our centre . After a speculum examination ,exfoliated cells in cervix is collected using a small brush .The brush head is then put in a cylinder with liquid fixative and processed in the lab. At the laboratory the liquid is treated to remove other elements such as mucus before a layer of cells is placed on a slide. The technique allows more accurate results.
