Rejection Reasons for HIV Viral Load and Early Infant Diagnosis Tests in Cameroon, 2024

Cameroon's national network of 17 HIV reference laboratories recorded sample rejection reasons for HIV viral load and early infant diagnosis testing from November 2024 to August 2024. The dataset, created by Marie Atsama-Amougou, includes 326,885 HIV-VL and 38,354 EID specimens received, with 12,748 (3.9%) and 1,039 (2.7%) rejected, respectively. It was last updated on April 27, 2026.

Use Cases

• Analyze the distribution of pre-analytical error types based on the rejection reasons mentioned in the description
• Model factors associated with sample rejection based on the recorded test type and error categories
• Benchmark laboratory performance against the national rejection rate target of <2% based on the reported rejection percentages
• Identify priority areas for intervention in laboratory workflows based on the frequency of specific errors like specimen identification or insufficient volume

Strengths

• Includes data from 17 national reference laboratories, providing a network-level view
• Reports specific rejection counts and percentages for 326,885 HIV-VL and 38,354 EID specimens
• Breaks down rejection reasons into quantified categories like identification errors (63.14%) and insufficient volume (43.7%)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data covers an 8-month period from November 2024 to August 2024, which may limit longitudinal analysis
