Can A Blood Test Tell Ones Race?
352787
There are certain identifiable characteristics that can be found in some blood samples. The most prominent example is Sickle Cell anemia.  \nThat's just from blood. However, from DNA markers, it is possible to identify certain genomes that would give you a pre-disposition to certain races.  It may not be a definative race, but it could narrow down possibilities until you can come up with a high probability.

Go and have a bloodtest ( chemists do it for free in the UK )\nyou might be diabetic !

often yes...but only approxiamatly....\n\nbut not always no...often this is false....\n\nbut then so is the large hands test....\n\nthe size and shape of the fingers.....(short thin fingers = short thin.....)\n\nand the height test (height= large thingy....)\n\nand even the "black" myth is untrue....

All great answers.\nIt is nearly impossible to determine race.  \n\nAnalyzing DNA in a petri dish you would be able to determine probably eye color, probably hair color, and some other identifying informaton. But not race. You could link to some degree of certainty the sample to a known population, but not with enough specifity to hold up in court.\n\nIn general, we as a species are all very similar. Distinct culture and populations have some unique traits that repeat due to the closed nature of that society but as a species we work out genetically to be quite the same. \n\nThink of it this way. If an alien came to Earth, took random samples of people from all over, they would conclude we are all the same. That any variations in structure or color must be normal variety in the genome.

Sounds like you may be starting.  Sometimes the blood can take on a brownish tint.

Please call the lab where you'll have the test done and ask this important question.  Good luck.

Bingo!  In fact, when doctors test for certain kinds of diseases, including HIV, they don't look for the disease itself, but for antibodies in your blood that are specific to that disease.

Is Your Blood Type Rare? \n\nMore recently, a number of characteristics, sometimes called markers and antigens, have been found in blood. We inherit these unique characteristics from our parents. Sometimes the process of finding compatible blood for someone with rare markers or a rare blood type is complex and challenging. Fortunately New York Blood Center has a team of world-renowned "match-makers" in our Immunohematology Lab who search for just the right compatible blood for a particular patient in need. \n\nIn fact, NYBC has the largest inventory of rare blood types in the U.S. - but we always need more rare blood. Almost everyday we receive a call from a hospital somewhere in the world trying to locate a rare blood type for a specific patient. These precise units are so rare, in fact, that we specially classify them as either "Code 99" or "Code 96" donors. Code 96 donors lack a particular combination of common markers, while Code 99 donors lack a marker nearly all other people have. Giving rare units of blood a special designation makes storage and, more importantly, retrieval of these rare units easier. That's also why we encourage donors to self-identify their ethnicity on our donor registration forms so the screening process for a rare unit of blood likely to be found within a specific ethnic group is streamlined for a patient in need.\n\nIt would be a really nice thing if you donated your blood.

First of all...to all the people that said "duh"...Your answers to this question were 100 times as stupid as the question itself.  The answer to the question is that they will only find out if you have AIDS, if you've done marijuana, or other drugs if they run a specific test for it.  They don't put the blood in a machine and have it run all the tests that are known.  When you get blood drawn, there has to be a reason...They might be looking for how your kidneys or liver are functioning, so they will test for that.  If they want to know if you have been taking drugs, they can test for that as well.

yes in blood, urine or hair samples....

A CBC or Complete Blood Count will not tell you of any diseases you have.  It tells if you have an infection by the elevated white blood cell count, it tells if you are anemic (low on blood) and it gives you a platelet count.  Those are the basics of a CBC blood test.  Testing for HIV or other autoimmune diseases require a different vial of blood and techniques in the lab.  Hope this helps

I do believe that there were people who lived in England decades and decades ago who were from African descent.  I have met several black people who were from England and their ancesters were from England many years back.  That doesn't necessarily mean that you have any black blood in you.  If you look a little exotic, that doesn't mean anything.  The caucasian race is widely diversified . . . there are blondes, redheads, brunettes, and those with black hair.  Their complexions range from the very pale to the very tanned.  I would consider you a caucasiion if your family tells you that you are.

The tests are very accurate. They are manufactured with certain controls built in, but you should follow all the instructions that you were given by teh clinic or whom ever will be drawing the blood.

This is a point that has been taken up by those in scientific and academic circles.\n\nSo, no, you aren't the only one.\n\nNot long before I was born, it was assumed that Black blood types must be different than Whites, and Blacks who wanted to donate blood were rejected.\n\nTurns out there's no relation between blood type and race.\n\nThere have been people arguing that the whole concept of race is bogus.\n\nA few weeks ago, I caught part of a really interesting documentary on PBS of a genetics expert who was following out the migrations of humans.\n\nTurns out, everyone in Europe, most of East Asia (northern, primarily) and the Americas are related, and descended from the same small group of people -- who had first migrated to the middle of Eurasia, then some traveled west to Europe, and a very few to the Americas.\n\nThe differences that have sprung up since the separation of people into the "races" are as nothing compared to our shared traits.\n\nAnd no one is "pure" as there has been mixing ever since.\n\nNo, you're both in good company and on solid ground in finding the concept bogus.

Yes! and there is help and many different reasons why you may be tried.  You need to make an appointment with your doctor and have them run some blood test.  You could be aniemic, or low on B12 or whatever, but let you doctor help decide.
