Convert the XYZ values to Lab using the following formulas. Note that we typically use the 2° standard observer for this conversion, as it is the most commonly used for color matching.\[X_n = 0.95047 \quad (\text{reference white point for D65 illuminant})\]\[Y_n = 1.00000\]\[Z_n = 1.08883\]\[f(t) = \begin{cases}t^{\frac{1}{3}} & \text{if } t 0.008856 \\7.787 \cdot t + \frac{16}{116} & \text{otherwise}\end{cases}\]\[L^* = 116 \cdot f\left(\frac{Y}{Y_n}\right) – 16\]\[a^* = 500 \cdot \left( f\left(\frac{X}{X_n}\right) – f\left(\frac{Y}{Y_n}\right) \right)\]\[b^* = 200 \cdot \left( f\left(\frac{Y}{Y_n}\right) – f\left(\frac{Z}{Z_n}\right) \right)\]
"Delaying reporting a case is indefensible," said Prof Paul Hunter, an expert in infectious disease at the University of East Anglia. "You don't wait for a formal diagnosis when it comes to meningitis – you report it straight away so it can be investigated.
