In many parts of Lagos, laboratory testing plays a major role in diagnosing infections. However, due to outdated testing methods, poor quality control, or over-reliance on lab results without clinical correlation, some infections are frequently overdiagnosed.
1. Typhoid Fever (Widal Test)
Many labs still rely on the Widal test, which can give false positives due to prior exposure, vaccination, or cross-reactivity. Blood culture is the gold standard but is less commonly used.
2. Malaria
Often diagnosed without proper testing or based on vague symptoms. Microscopy with proper technique or high-quality rapid diagnostic tests give more accurate results.
3. Urinary Tract Infections (UTIs)
Presence of white blood cells or bacteria in urine without symptoms doesn't always mean infection. Urine culture is needed to confirm and identify the right antibiotic.
4. Staphylococcus Infections
Staph aureus is part of the normal skin flora and doesn't always mean infection. Diagnosis should be based on symptoms and clinical judgment.
5. Candida (Yeast Infections)
Presence of Candida doesn't always mean an active infection. Treatment should only be given when symptoms are present.
Why It Matters
Overdiagnosis leads to unnecessary drug use, increased resistance to medications, wasted resources, and delayed diagnosis of the actual illness.
Conclusion
Improving lab quality, updating diagnostic protocols, and correlating test results with symptoms are key to reducing overdiagnosis.
