Fresh voided urine The container is clean and sterile (for culture )
The sample must be tested within 1hr

When urine is clear that mean urine is free from WBC, RBC, Bacteria , epithelial cell.
If urine is turbid we can found WBC,RBC ,Bacteria.
2-color :Normal color for urine is straw ,pale yellow ,light yellowAbnormal in color colorless , dark
yellow ,red……
3-spacific gravity: Measure urine density or amount of solute in urineNormal SG for urine 1.025 Excessive water intake SG low
4-PH:Normal urine PH is (4.6-8.0) as averagen6.0
CHEMICAL EXAMINATION 1-protein:
Test protein in urine by:Urine strip
Sulfosalicylic acidHeating and cooling for bence jonce protein in multiple myeloma patients
2 -Glucose: Under normal condition all most all of glucose filtrated If blood glucose is increase up to 180 mg/dl glucose appear in urine ( threshold value )
3 -blood 4 -keton body
5-nitrite: Apositive nitrite test indicates that bacteria may be present in urine

7 -crystal IN acidic urine ( ca oxalate , amorphous urate, uric acid )IN alkaline urine (ca phosphate , triple
phosphate, amorphous phosphate )
