To confirm a suspicion of hypervolemia, which test is most indicative?

Daily weight is a highly effective and indicative measure for confirming hypervolemia because it provides a direct and immediate assessment of fluid retention in the body. Rapid increases in body weight, particularly when monitored consistently over time, can signal an excess of fluid volume. This is especially useful in clinical settings, where small changes in weight can provide significant insights into a patient's fluid status.

In contrast, blood pressure measurements can vary widely due to multiple factors, including medication effects, body position, and stress, making them less reliable for diagnosing hypervolemia specifically. Urinalysis can provide information on kidney function and fluid balance but does not directly indicate total body fluid volume. An electrolyte panel can help assess imbalances related to fluid status but doesn't directly reflect hypervolemia itself. Therefore, tracking daily weight is the most practical and sensitive method for monitoring and confirming fluid overload in patients.
