- Monitor conditions such as diabetes, hypertension, and kidney disease.
Procedure:
- Collection: Clean-catch midstream urine sample.
- Analysis:
- Visual Examination: Assess colour and clarity.
- Chemical Examination: Dipstick test for glucose, protein, ketones, haemoglobin, and pH.
- Microscopic Examination: Identify cells, bacteria, crystals, and casts.
Key Indicators:
- Colour and Clarity: Clear, light yellow.
- pH Level: 4.5-8.0.
- Specific Gravity: 1.005-1.030.
- Protein: Normally none or trace.
- Glucose: Normally none.
- Ketones: Normally none.
- Haemoglobin/Blood: Normally none.
- Leukocyte Esterase: Normally none.
- Nitrites: Normally none.
- Microscopy: Cells, bacteria, crystals, casts.
Routine Stool Test
Purpose:
- Diagnose digestive tract disorders and infections.
- Screen for colorectal cancer.
- Detect malabsorption syndromes.
Procedure:
- Collection: Small stool sample in a clean container or special collection kit.
- Analysis:
- Visual Examination: Assess colour, consistency, blood, mucus.
- Chemical Tests: Detects occult blood, fat, digestive enzymes.
- Microscopic Examination: Identify parasites, ova, bacteria.
Key Indicators:
- Colour: Brown (normal); deviations indicate various conditions.
- Consistency: Formed (normal); watery or hard indicates GI issues.
- Occult Blood: Normally none.
- Fat: Normally none or very low.
- Parasites and Ova: Normally none.
- Bacteria: Specific flora (normal); pathogenic bacteria indicate infection.
- WBCs: Normally none; presence indicates inflammation or infection.
Routine stool and urine tests are essential for diagnosing and monitoring various health conditions, involving straightforward collection and detailed analysis. These tests provide crucial data for early detection and effective management of diseases.
