¶1A jury found Chevy Harrell guilty of driving under the influence of drugs and alcohol to the extent that it was less safe to drive, driving under the influence of cocaine, and driving with a suspended license. Harrell appeals, alleging the trial court erred in admitting the results of her urine test into evidence because the state failed to establish a sufficient chain of custody. We find no error and affirm Harrell’s convictions.
¶2The record shows that after her arrest for driving under the influence, an officer with the Rockmart Police Department took Harrell to the local .hospital for a urine test. At the hospital, the officer opened a sealed blood alcohol kit, took a urine sample from Harrell, *178and gave the sample to a nurse. The officer watched as the nurse sealed and wrote on the sample. The urine sample was sealed first within a cup and then within a Styrofoam container and a box. The sample was labeled and sealed in the appropriate kit. The officer then gave the sample to a different officer, who placed the sealed container in the sealed police refrigerator.
¶3While no evidence was presented regarding the transportation of the sealed container to the crime lab, a crime lab employee testified that she received the sealed container, that it was still sealed, and that it showed no evidence of tampering. The sealed container was labeled as being collected by the Rockmart Police Department on the date of the incident. According to the crime lab employee, everything was properly labeled and sealed, except the defendant’s name was spelled Chevy “Harold” instead of Chevy “Harrell.” The state further presented evidence that the labeling of the sealed container was done by the hospital nurse and that the officer never spelled the defendant’s name for her. Rather, the nurse asked the defendant about her name.
¶4We find no merit in Harrell’s claim that the state failed to establish a sufficient chain of custody.
Where the State seeks to introduce evidence of a fungible nature, it must show a chain of custody adequate to preserve the identity of the evidence. The burden is on the State to show with reasonable certainty that the evidence is the same as that seized and that there has been no tampering or substitution. The State need not negative every possibility of tampering, and need only establish reasonable assurance of the identity of the evidence. When there is only a bare speculation of tampering, it is proper to admit the evidence and let what doubt remains go to the weight.1
¶5We have reviewed the chain of custody evidence and find that the state established reasonable assurances of the identity of the urine sample.
