As of my last update, DNA testing services were limited in Sudan due to various factors, including infrastructure challenges and the availability of laboratories. However, some private clinics and international organizations may offer DNA testing services. It's advisable to check with local healthcare providers for the most current options available in the country.

Usually water is the best control substance for the Sudan IV test.
Ive searche on the Internet to find an answer to why it's called the 'Sudan' Iv test, but I haven't found a clear answer, but my guess is that the things used in the test, was first discovered in a mine in Sudan, that or the inventor was Sudanese
Like lipids, the chemical Sudan IV is not soluble in water; it is, however, soluble in lipids. Therefore to test for the presence of lipids in a solution you will use a Sudan IV Test. In this test dark red Sudan IV is added to a solution along with ethanol to dissolve any possible lipids. If lipids are present the Sudan IV will stain them reddish-orange, giving a positive test.
Egg yolk should have a reaction in the Sudan IV test, because the Sudan IV tests for lipids (fats), and the yolk does have some fat in it. The Sudan IV test should have not had a reaction for egg membrane or egg white. Hope that helped!
to test for the presence of lipids.
Sudan III test
lipids
The Sudan test for skim milk is negative because skim milk contains little to no fat, which is the primary component that the Sudan dye detects. The Sudan dye specifically binds to lipids, and since skim milk has had most of its fat removed, there are insufficient lipids present for the test to yield a positive result. Consequently, the absence of fat in skim milk leads to a negative outcome in the Sudan test.
Sudan IV is a chemical that is only soluble in lipids. This indicates that a positive Sudan IV test means that the food is a significant source of lipids.
Walgreens offers the Identigene DNA paternity test, which can also be purchased from the Walgreens website or Identigene's own website. To find other stores carrying the product, the Identigene website also features a "Find a Store" function. For those preferring a different test, the Home DNA company has its own product available online, from the company's website.
