Section 3 - STD Management

Laboratory-Based Approach

  • Laboratory tests used to identify infectious agent

  • Most precise method

  • Requires substantial resources

  • Treatment usually delayed

Slide 52

With this approach, laboratory tests identify the infectious agent. If used correctly, the laboratory-based approach is the most precise method for diagnosing and treating STDs. However, this approach requires substantial resources. In developing countries, laboratory tests are often not available at the primary health care level, where the majority of patients seek care.

To use this approach, skilled technicians must be trained and supervised. Generally, specialized and expensive equipment is needed, along with reagents and other supplies for laboratory tests. In addition, many laboratory tests require reliable electricity and water supplies, which may not be available in many settings. Researchers are trying to develop less expensive laboratory diagnostic tests.

With the laboratory-based approach, treatment is usually delayed until test results are available. This may take several days. Thus patients often must return for treatment. Those patients unable to return to the clinic will not receive treatment.

Theoretically, this approach can be used to diagnose infection in anyone, including those with no symptoms. In practice, however, asymptomatic persons do not usually seek tests to determine if they have an STD.
