What must be done to protect amniotic fluid from light?

To protect amniotic fluid from light, covering it with aluminum foil is the most effective method. Amniotic fluid can contain sensitive components, such as bilirubin, which can degrade when exposed to light. By using aluminum foil, you create a barrier that blocks light from reaching the sample, thus preserving its integrity and preventing any potential chemical changes that could affect laboratory results.

While storing the sample in a dark room or using an opaque container may provide some level of protection, they are not as effective as directly covering the fluid with aluminum foil. Refrigeration, while important for maintaining temperature, does not shield the sample from light exposure, which is why it does not fulfill the specific requirement of protecting amniotic fluid from light.
