Answer 1

Just describe what happens so that doctor can diagnose it properly. You will probably be asked lots of questions, stuff like when it happens, how you feel before it happens, for how long you lost consciousness, what were you doing right before it happened, has anything changed right before it happened, and how are you feeling other that that - stuff like that. If you can spend some time thinking about those experiences and even write them down so you will remember, that give the doctor more information, which is a good thing. Whether they give you a blood test will be determined by what they think is wrong. They might have a few different guesses and try to use tests to rule out things. If they did want a blood test, a typical blood test might test for red and white blood count (red is hemoglobin) - a high white count would mean you have an infection, a low red blood cell count would mean you have anemia. Whether it hurts or not depends on how good they are at drawing blood. Many doctors offices will write you an "order" for a blood test, and have you go to an independent lab that draws the blood. The people there are experts, so it won't hurt much at all. The two biggest chains of labs who do blood tests are Quest and LabCorp - your parents will probably check to see which one is hooked up with your health insurance.

They will probably start by checking your blood pressure and asking you about any other symptoms you may have. If they decide to check your blood, they may get you to fast for the test, so they can check your blood sugar levels. They will also check your blood count and look for nutrient deficiencies. Being too low in certain minerals like iron, zinc or B12 is a common cause of anemia, which can lead to low blood count. They can also check for hormones levels, and infections



Blood tests are scary to some, but don't really hurt all that much if you are relaxed. They are only painful if you expect them to be. The only part that really hurts is when the needle first goes in, but that's like 1/2 second (If you've ever had your ears pierced, it's similar) Once it's through your skin, it just feels like a tube is touching you. You can't feel it inside you. I usually chat with the nurse if I'm a little nervous. Most are more than happy to explain what they are doing and why

Answer 3

Well first off they will be asking you a bunch of health questions, the doctor will examine you which is just looking at and feeling different areas and listening with a stethoscope, they will be weighing you, checking your vital signs and probably put some stickers on your chest to see your heart rhythm. They may or may not think you need a blood test. If they do a blood test, it will probably include complete blood count (CBC) which includes hemoglobin and hematocrit (whether you have enough red blood cells), white blood cell count (too high could indicate infection), platelets (they are what make your blood clot when you get cut). Along with this they will send a metabolic panel which includes sodium, potassium, glucose, chloride, co2, bun and creatinine (gives information about your electrolyte and fluid levels, blood sugar and kidney function). These two tests alone along with your vitals, hearth rhythm and the doctors assessment will give the doctors tons of information about what could be going on. Passing out (syncope) could be because you are anemic (not enough red blood cells), because you are dehydrated, because of low blood sugar, or because of abnormal hearth rhythms, and tons of other causes. Some people just pass out if they stand up to fast and have to get up more slowly, but there is nothing wrong with them. Usually syncope does not turn out to be from a serious disease. Unfortunately, oftentimes doctors aren't able to figure out why someone had syncope. This is what happened to me. I passed out a few times over a few months when I was about 19. They never figured out what was causing it, but it went away on its own.

Answer 4

It depends on who draws the blood. Some people are very good at their job.



There are a lot of things they test for. The doctor will make the list out for the

testing laboratory.



It will be ok, don't get all upset worrying.
