Once radiopharmaceuticals enter the body and travel to an organ, they begin to interact with the processes of that organ. The radioactivity is picked up by cameras or computers and used to map the process. For example, an ultrasound can show an image of an organ and reveal if a tumor or other abnormality is present. Nuclear medicine can show how the process of glucose metabolism is functioning in the organ.
250g bags of our biltong can last up to 4-months, and we have food testing certificates to prove this, however, we do not advise that you keep it that long. The larger the bag of biltong, i.e 500g or 1kg, the more moisture is contained within the sealed bag.
A-Samples should be stored in a refrigerator. If stored for extended periods of time then they should be frozen. The integrity of our samples is ensured by our proprietary vacuum seal. As long as the sample remains in its vacuum seal it may be kept at room temperature away from direct sunlight for days at a time. It will be good for up to six months, in the vacuum seal, if stored in the refrigerator. If frozen in the vacuum seal, it can last for about 1 year. Once the sample is removed from the vacuum seal, it should not remain at room temperature for more than 18 hours. It will keep in the refrigerator, unsealed, for 30 days. In the freezer, an unsealed bag can last up to 6 months.
