What would be a good size sample for a āharvestā? Letās say a 100# harvest, what would be the amount needed to get a more accurate result?
Sorry if Iām using basic terms, Iām just a layman trying to follow along.
Well the rule they ultimately settled on in Oregon was the following:
They donāt let you test a batch larger than 15 lbs anymore, and it takes 35 grams for a test of that size. And then they would test it in 9 increments. In concentrates on the other hand, they would let you do a ācontrol studyā where if you showed your product was homogenous once, theyād let you combine all the samples drawn in future batchss into one increment and just test it twice. They do this to help you save money and processors more or less insisted on it.
However I donāt think this is really scientifically legitimate. The problem is that leaves you extremely vulnerable to lab mistakes. Only doing one test hits you with a big random error, and it also means a lab technician only has to mess up once and your result is going to be completely off. For better accuracy every increment pulled should be tested independently. You should be doing 10-20 samples on every batch of oil. Thatās considered small in water testing. Then maybe you might start to approach precision and accuracy.

But without some kind of regulation to limit and control the cost of testing, compliance could bankrupt companies. The cost of a control study is outrageous (usually 6K+), and if the cost for testing each batch were equal to that of a control study, many could not afford testing. Whereās the middle ground?

The middle ground is accept that mistakes will happen, work with your lab, and if their report makes no sense to you work with them to explain why itās impossible and conduct retests. The technicians who prepare the sample only see a number, they donāt really know anything about how the product is prepared or have any ācommon senseā about it. To solve an error there needs to be communication between you and them.

Unfortunately they donāt understand this a lot of the time and tell us āthatās the right resultā¦ā even after we explain to them how itās impossible. So idk there has to be some sort of change across the board

Is this in comparison to your own in-house analytics? Usually that is grounds for the beginning of this type of conversation. And yes, it sucks, but this is the way we have to conduct business, for now. The way @MagisterChemist suggests as the middle ground to not bankrupting yourself with testing costs is the way that I have been having to do it for years. It came from watching people much smarter than myself. If they donāt understand, help them to do so.
The better we can educate them, the better testing will be. Just like here: try to share the knowledge and maybe make some friends on the process. Not always fun, but the struggle makes the successes that much sweeter.

Iāve never had any trouble with any lab refusing to work with me on results, and iāve used a lot of them. Considering the title of this thread, is it possible maybe youāve been taking a confrontational approach with them that is making them not want to talk to you? I definitely had a lot of clients making complaints along the line of āthis weed canāt possibly be 15% itās super fireā and not contributing any real data or helpful comments, and you get used to shutting down people if thatās the direction theyāre going with

Point taken.
None of us work in the hemp industry, regulated by the FDA, USDA, State Dept of Agriculture & DEA, 50 different state controlled substances regulations, 50 different state pilot hemp programs which require compliance to sell in each state.

I have been selling into the Pharmaceutical market for 15 years. I get it. I also get that there is no difference between cGMP and GMP but why would I be complete ass and call out a smarty pants like @Siosis? I think he probably has a good point in mind that wasnāt fully formed.
My point about GMP is that it is like an ISO certification. You can make a completely crappy product and be ISO certified. It is a process certification. You can have a great process and develop a lousy product. Round-Up life killer is produced in a certified facility.
If you are interested in learning about process development, auditing and constant improvement, here are some simple reads that assist with that mindset:

Nah not at all. Canāt take a confrontational approach to the labs because there Arnt many options. God forbid I take a moment to express my COA PTSD to a group of people who have also experienced the nonsense that is testing.
I think your totally misunderstanding whatās happening here. Now there are some labs that absolutely are just lost causes and will never figure it out.
But most labs work with you and figure out whatās going on and what happened. And thatās what has to happen. But if I had to explain to my clients why there was an issue with their extract every time I did a contract for them Iād be out of business. But it is what it is so we keep working with them and try to make the best of an unfortunate situation. You and the other guy are taking this at face value like Iām calling around bitching out my local labs like āWhy you no give me 90% COA! It fire fire bro it has to be 90%!ā Nah not at all
I know you know what gmp is.

This times a thousand. Just cause you have a certification definitely does not mean that your products are now Guaranteed to be superior.
Which for some reason is the assumption in the industry.
cgmp and GMP are like 2-3 steps away from each other
