They didn't test my sample for 4 days. On fifth day it was inconclusive. I took one pcr test on Friday 08.10.21 because I wanted to be sure before flying to see my 99 and 93 year old grandparents. It is not a legal requirement for me to take a covid test before flying because I am vaccinated. I flew on Sunday 10.10.21 and my result still had not arrived. The sample was only tested at 7pm on 12.10.21. This is four days after the sample was taken .I received the result on Wednesday morning 13.10.21, five days after I'd done my sample. My sample was collected on Friday. When my result eventually arrived five days later, it was inconclusive. I'd been about to see my very elderly Grandparents. It caused a huge amount of worry and inconvenience.Therefore I had to pay £90 for another PCR test in Germany. I asked Dante for more information and when I'd get the result retaken. No one replied except an automatic apology response that ignored my questions. Therefore I had to pay £90 for a PCR test and isolate until I got the result. I could not see my Grandparents and it was a huge amount of stress for me and my family who have disabilities. The result of the second German PCR was negative. The original sample was retested by Dante lab and was negative at 3pm 14.10.21. I got my correct result 7 days after I took the test and during that time severe stress, expense and inconvenience as well as ruining my seeing family. I was there due to a death in the family and it was already very stressful. I had not seen them on three years and this situation was completely avoidable. Do not use them. They took five days to get my result and it was inconclusive presumably because it took so long. Shocked.
