Which serous fluid characteristics indicate a transudate?

Transudates come from imbalances in hydrostatic or oncotic pressures, so the fluid that forms is typically clear and low in protein, LDH, cholesterol, and overall density. This contrasts with exudates, which result from inflammation and have higher protein and LDH content and often higher density or cholesterol, and may appear turbid or bloody. The option described as pale yellow, clear fluid with very low values across the board (TP under 30 g/L, low protein, LDH under 0.6, cholesterol under 1.2, SG under 1.015) fits this pattern of minimal protein and enzyme content and a low-specific gravity appearance, indicating a transudate. Other options show signs more typical of exudates—for example, turbid or bloody appearance with higher protein and LDH, or higher density—so they are less consistent with a transudate.
