Rainbow Labs Reviews 

I bought the test on Thursday night, which was sent on friday and arrived on Saturday.
After I uploaded the result photo (negative), it took less than 1 minute for my certificate to arrive from their certification team.
Before buying, I decided to reach out for support via email, and my reply came within 4 days.
Excellent experience!!

It has been a week since they've received my test and I've got no results yet. A few days back, they replied back to me saying they have gotten my test and are processing it, and still no results! I've asked for a refund twice and they have ignored me

I still haven't received the results 10 days after sending the sample to the lab. Why is the government not removing them from their approved list of providers?

Avoid at all costs.

After one week I am still waiting for my test results.
The worst provider I have found in two years of pandemic.

This is not only a PCR result, it is more than that, It is the health of myself and the rest of the people around me. I have received my 2day PCR result 138h after they received my samples when it is supposed they should have been released 48h maximum. Awful service. I had to call them 7times to get any info but they did not give me any explanation at all. They just told me that small thing had to be done and I should wait a bit more. They do not take notes in their system, so when you call them again, you have to explain everything again. They ended up my phone call to not have to explain anything. They do not send the emails they promise you during the conversation. They do not have any company structure, it seems that they are plenty of managers and none of them take care of the issue, for instance, the manager Charlie did not want to speak with me and he never sent to me an email with an explanation. When you ask about a refund, they say that they do not have a refund policy, even when they do not give the service agreed, results before 48h.

Terrible service. The test kit took way too long to arrive. I requested a refund after a few days time but they said they could not offer a refund as it had already been sent. I waited another couple of days then contacted them again. They then said they would send me out a new kit and still refused any refund!
Eventually I got the kit, sent it back, and I have never received a result back since! I ordered on the 18th December and it is now 17th January! Shocking! Avoid at all costs!

Use anyone else unless you want your holiday ruined of you want extra quarantine days.

I'm just following up on my review from last week. It's day 16 and I still do not have my day 8 results. Worse, they tried to re-send my day 2 results as if they were my day 8 results, not even bothering to change the date and time stamp on the day 2 results so the trick was rather amateurish.

This company is horrible, bordering on criminal. I only used them because the companies I usually use were not available and we desperately needed a testing code to reenter the UK after travel. Avoid at all costs.

SCAM company. AVOID.
I am still waiting for my PCR test result from Jan 4th.
Today, 10 days later and no result but a paltry response from Rainbow labs telling me "be patient and wait." Ridiculous.
There need to be stricter rules to hold companies to account if they fail to keep the promises made on their websites.

I paid £49 for a day 2 PCR test, which was sent to them over a week ago. I have emailed, only to be told to give them more time to process it! This certainly appears like a scam, yet on the list of approved providers by the government!
Thankfully the rules changed just as I returned to the UK, so didn't have to self isolate until I had the results, or I would have lost work as a result.
Avoid this company like the plague!!!!

The worst experience ever. Test came back saying that’s it’s unclear. Either it’s negative or it’s positive (how can it be unclear), got me on a roller coaster. They tell you to get in contact with them immediately but when you are on the phone ringing them, you end up in a queue. After waiting for your turn reaching to queue no 1, the end the call saying that there is no one available to take the call. Absolutely BS of a company. Terrible customer service. Definitely never to deal with this company, stay far away.

Three Day 2 test results never arrived. They tried to blame us saying we had not activated the test, which we did.
This company is playing with public health and should be accountable for that. Let alone that they are scamming hundreds of citizens without anybody moving a finger.

So it’s 8 days later, and I’ve STILL not had my results back. It’s all BS. Emails go unanswered and phone calls just fob you off with “it’s still processing”. Stay clear. Should be removed from the gov website as they’re clearly under prepared and possibly a scam at this point. If I could give 0 stars I would.

TL;DR: Potentially scamming money now and not even bothering to run the tests.

I won't be surprised if I hear that this is a ghost company operating from some lawless country.

I bought a PCR day 2 test. The test arrived ok, and I posted my sample on 6/1. I didn't get the results for several days, and because I want to be fair I checked first with Royal Mail. Royal Mail confirmed that my sample was delivered on 7/1.
So I called them and they told me that my sample had not been activated (which I had done).
They asked me to activate it again, which I again did and called the following day.
Once again I was asked to activate for a 3rd time. I did and called them back, only to be told that they can't see my activation!
This time I could reply that "I have open the site where there is a message that 'activation successful'". They asked me to send the screenshot and activate a 4th time. This time they replied that the activation was finally found...
I expected that I will receive the results...
Since I received nothing, I emailed them again. On 15/7, 8 days after they received my sample, they replied me that "we don't do refunds... you can use the sample on another occasion(!), and they blamed Royal Mail for no delivery.
I'm taking the matter forward, but I'd rather not need to.
STAY AWAY!!!

Stay clear if you actually want a result. Sample received at the lab more than 96 hours ago and when I call advised to call back. No response to email.
To get the reference to be able to board plane they were cheaper than others. But if you actually want a result stay clear.

Avoid. They sent the test kits quickly but its been 5 days and I still don't have my test results. I would not use them again unless you want extra quarantine days. Worse, I emailed and called several times. No help, just jawjaw. Again, avoid!

The pack was tracked to delivery.

The worst experience ever. First of all my test results were sent 63h after I took my test (on the website it says a 48h). Secondly, they came back as unclear which doesn't make any sense. What does it even mean?! I took a number of lateral flow tests which came back negative. Don't use them, waste of money.

Rainbow Labs suggests using Royal Mail for the delivery of PCR tests.
First of all, they delivered my 2Day test in the afternoon of the actual second day after my arrival.
Secondly, I used the Priority box of the Royal Mail to send it back to the laboratory. The RM collected the test the day after I dropped it. Then, they delivered it early in the morning the NEXT day.
And finally, Rainbow labs took the test to analyse only the next day, e.g. 3 days after I've done it. It is obvious, that the result was unclear and they suggested to BUY ANOTHER TEST without any refund.
DO NOT USE THIS SERVICE.

My day 2 test came on time after i arrived in the UK and I received my results the day after. I thought it was a scam after all the reviews but my order proved otherwise.

After the shambolic error of receiving someone's actual test swab in the post from Rainbow Fulfilment (review 01.01.2022), I eventually received an email from the Manager RAJA
He is the Manager of the Gov appointed lab "ARRIVALS DIAGNOSTIC", and his logistic partner is "RAINBOW FULFILMENT," which send, receive and do the packaging ( which leaves me to wonder who actually does the lab testing, and where..).
Raja acknowledged it was a serious mistake, and has actually refunded the cost, and wrote..he will "investigate the matter".
But I do not trust these companies, and have written to 3 MPs, urging them to scrutinize their reliability.
I originally ordered a test kit from ARRIVALS DIAGNOSTIC, which I received, and sent off my sample ,after Christmas...but received a Neg result ...not from ARRIVALS DIAGNOSTIC...but from the NHS !!!, who I had not contacted at all. Obviously, because they were closed over Christmas, they must have sent all test samples to the NHS to analyse, in which case we need not have paid at all..and that is why I demanded, (and got) my refund.
