Can you use the post office?.

There are strict guidelines to sending diagnostic samples via the post office in the UK and also from around the world so we hope the following helps you. Generally specimens are referred to as a Biological Substance and are covered under a category of pottentially hazardous goods known as UN3373 Biological Substances Category B, so this really refers to anything that could leak or drip

Q1: Does your have a liquid component ?  If No, then you can send it via the post office
