Positive and negative drug controls are necessary to test the validity of drug tests. Just as scientific experiments use a control group to compare their results to, drug controls are used to make sure that a drug test is making a correct reading.
Both negative and positive controls are offered for purchase at drugtestsinbulk.com. Drug testing validation can be a bit tricky for unseasoned professionals, however each of the products offered at drugtestsinbulk come with a full set of instructions. Also found with instructions on page are precautions, how the product should be stored, appropriate procedure, limitations of procedure, detect abuse of THC, and detect abuse of oxazepam.
The product seems to legitimate for the validation of drug testing results, but only when used with quantitative or qualitative measurements. The product is sold in small, 5 milliliter bottles. According to the description two of the bottles would be necessary per test for cup methods, and only one would be necessary for dip tests.
The pricing of the positive and negative controls is fairly reasonable at $17.50 per negative control and $18.00 per positive control. The item is intended to be used by healthcare professionals, but checkout does not ask for any sort of validation that you are a healthcare professional. If a company desired to, they would be allowed to purchase up to nine hundred, ninety nine thousand, nine hundred and ninety nine bottles of either positive or negative controls. There don’t seem to be any extra discounts for bulk orders, however the standard pricing on the site is already nearly half-off the standard item pricing.
