Universal Health Coverage (UHC) aims to ensure that all individuals receive needed health services without financial hardship. Discussions around UHC often focus on financing mechanisms, insurance coverage, and treatment availability. Yet a fundamental component is frequently overlooked: diagnosis.
Healthcare begins not with treatment, but with understanding the patient’s condition. Without accurate diagnosis, treatment may be delayed, inappropriate, or ineffective. Medicines cannot be used rationally if the underlying illness is unknown.
In many low- and middle-income countries, patients frequently receive treatment based on symptoms rather than confirmed diagnosis. This occurs not because clinicians disregard evidence-based care, but because diagnostic services may be inaccessible, slow, or unreliable.
The consequences are significant. Patients may purchase multiple medications before receiving correct treatment. Families incur repeated expenses. Antimicrobial resistance increases due to unnecessary drug use. Health systems spend resources inefficiently.
Accessible diagnostics improve both quality and efficiency of care. A timely test result reduces repeat visits, shortens illness duration, and prevents complications. At system level, it ensures that limited medicines are used appropriately.
Primary healthcare cannot function effectively without reliable diagnostic support. Facilities require either on-site testing or dependable referral pathways. When diagnostic services are integrated into routine care, clinicians make more confident decisions and patients trust the health system.
UHC therefore requires not only financial protection and service availability, but also diagnostic accessibility. Expanding treatment without expanding diagnosis risks increasing costs while limiting impact.
Health coverage becomes meaningful when patients receive the right treatment and that begins with the right diagnosis.
