What is albumin?
Is there albumin in milk, really? I did not realise that until I read about it recently.
Then, how come I can drink fresh milk but not have hard-boiled egg whites?
Obviously albumin is a collective class of proteins (I believe that is what wikipedia says), so that the albumin in egg white is different from that in milk, am I right?
Is it possible that people can be sensitive to one implementation of albumin but not sensitive to another?
Is it possible for people to be lactose tolerant but intolerant to milk albumin? Could there be people who think they are lactose intolerant, but are actually milk-albumin intolerant?
Therefore, the actual question is:
Is albumin intolerance differentiable by the albumin type or implementation? Do different people have intolerance to different albumin implementations?
P.S. I am using the term "implementation" because it is Java speak, and do not have the expertise to know a better or actual term to use.

I think this question would be more suited for Biology beta, but since it's here, I'll try to keep the answer as lay as possible.
Albumin, like you read on Wikipedia, is a large group of proteins, which are present in all kinds of organisms, including your own blood. (Actually, albumin in your blood has a very important function - it binds small molecules, such as ions or medicines, making them harmless to the body.) Albumin from one organism is not just one kind of polypeptide, each species produces many kinds of albumins. Therefore, albumins are present in your blood, in egg-white and in milk, but they are somewhat different proteins.
About lactose and albumin intolerance. There are two kinds of resposne - intolerance and allergy. Intolerance baisically means, that your body lacks mechanisms to break down a certain particle (e.g. humans are all celulose-intolerant), so eating intolerable food usually doesn't hurt more than some belly pains or a day of diarrhea. Generally, all proteins can be digested, but not all carbohydrates, so it's common to be lactose-intolerant but have an allergy towards egg-white.
Allergy on the other hand means, that your body is trying to "kill" the intruder, even if it's as harmless as a molecule of foreign albumin. Every molecule that triggers this immunologic response has haptens. These are in fact small parts of the molecule, that are "visible" from the outside. Since all organisms produce different kinds of albumins, the haptens of those albumins are different. That's why albumins from one organism may trigger allergic response and from other are tolerated.
Now, given all this basic information:
yes, people can be sensitive to one implementation of albumin but not sensitive to another;
yes, people may be lactose tolerant but intolerant to milk albumin, though "tolerance" is probably not the right word here;
and yes, there might be people who think they are lactose intolerant, but are actually milk-albumin intolerant, but it's not very likely.
Pictures about "What is albumin?"
What does albumin do in the body?
Albumin helps move many small molecules through the blood, including bilirubin , calcium, progesterone, and medicines. It plays an important role in keeping the fluid in the blood from leaking into the tissues.What does it mean if your albumin is high?
An albumin blood test checks levels of albumin in your blood. Low albumin levels might indicate a problem with your liver, kidneys or other health conditions. High albumin levels are typically the result of dehydration or severe dehydration. The test is very quick and doesn't carry any serious risks.What does a low albumin level mean?
Low albumin levels can be a sign of liver or kidney disease or another medical condition. High levels may be a sign of dehydration. Albumin is a protein made by your liver. Albumin enters your bloodstream and helps keep fluid from leaking out of your blood vessels into other tissues.What causes a low albumin level?
The most common causes of hypoalbuminemia include: Liver disease. Heart failure. Malnutrition or a vitamin deficiency.Getting to know albumin physiology

Answer 2
You can be tolerant to lactose but have a sensitivity or intolerance to milk albumin. My son is not lactose intolerant, but he does have a severe sensitivity to milk proteins (whey, casein and albumin) so we just avoid dairy all together.
