what determines your blood preasure?

There are many things that determine your blood pressure, or the pressure of your blood within your arteries.  Here are a couple:\n\n* The ease of your blood passing through your arteries (or conversely the restrictions of your blood passing through...)\n* The permeability of your capilaries\n* The make-up of your blood (usually the amount of salts)\n* Your Heart and how hard it is beating\n* The amount of blood you currently have (If you lose a lot of blood, you will have low blood pressure - not what you want though)\n* Certain drugs can have other types of effects.\n\nJ

No such thing can be determined by blood test.  There are usually questions, filling out tests, psych exams, etc. to determine such things.\n\nA diagnosis of ADHD is based on a checklist of symptoms from DSM-IV-TR.\n\nClinical Guidelines\nThe American Academy of Pediatrics Clinical Practice Guideline for children with ADHD emphasizes that a reliable diagnosis requires:\n\nThe use of explicit criteria for the diagnosis using the DSM-IV-TR. \nThe importance of obtaining information about the child’s symptoms in more than 1 setting (especially from schools). \nThe search for coexisting conditions that may make the diagnosis more difficult or complicate treatment planning. \nItem 1. is dealt with by using an ADHD-specific instrument such as the Connor's Scale. The use of methods such as questionnaires that attempt to identify other conditions as well as ADHD would not meet this requirement. Diagnosis based on a clinician's, teacher's or parent's opinion, without the use of a scale such as Conners would also be invalid.\n\nItem 2. emphasizes that the DSM-IV requires that the behaviors be present in more than one setting, normally school and home. (This is a significant change from the DSM-III criteria - see #Historical background). A diagnosis based on the a Connors Scale completed only for one setting would therefore be invalid.\n\nThe requirement that it be present in two settings is important because in the majority of cases observers in different settings do not agree on the child's behaviour. In studies that used both teachers and parents in the United States, Canada and Australia the difference has been significant. For example, one of these studies (Wolraich, 2004) found American teachers identified ADHD in 25.5% of a group of 6,171 children but parents identified it in only 7.8%

From the colour of the blood? No.\n\nThe only way to determine your blood type is through serotyping. Antibodies are added to a blood sample, and blood type is determined by whether or not agglutination occurs.

It varies.\n\nSometimes it is A positive,\n\nSometimes it is O positive.\n\nYes, I know it cannot happen, but that is how the test results come back.\n\nOh, and the red blood cells are being eaten by the white blood cells.

You need to fast to get accurate blood lipid profiles because these blood lipids are affected by what you eat.  If you have a high-fat meal before having blood drawn, the fat in the food will be absorbed, raising your blood triglycerides, which will falsely elevate your LDL cholesterol readings.  Fasting ensures that you can get a consistent reading without the effects of dietary fat.

(1) You can donate even without knowing your Blood Type.\n(2) Blood Group test is performed at almost every hospital. Result is obtained very shortly which allows you to know the type of yuor Blood Group.

A sphygmomanometer (note spelling) works by completely cutting off the blood flow with high pressure, and then gradually decreasing that pressure until blood flows again.  The nurse determines this by listening with a stethoscope.  When she first hears blood begin to flow with a loud sound, that is the systolic blood pressure.  When the sound is no longer heard, that is the diastolic blood pressure.  So the cuff just reports how much pressure it is applying.  The nurse has to determine at what point the body responds.

The presence of blood from your period will not affect the drug test. The test is looking for drugs and blood does not mimic any of the chemicals they are looking for which are actually the end products of metabolizing illegal or abusable perscriptions drugs

I believe it is geneticly pre determined.  either you are or your not!

The red blood cell (RBC) count determines the total number of red cells (erythrocytes) in a sample of blood. Examination of the erythrocytes provides the doctor/physician with information concerning anemia-related problems and the bone marrow response (which is where RBC's are produced). \nAnemia is basically deficiency of blood in common language.\n\nWhite blood cells (WBC's) are part of the body's defense or immune system.The WBC count provides clues about certain illnesses, and helps physicians monitor a patient's recovery from others.\nBasically WBC count says all about our immunity.The elevation or decrease in WBC decides our disease-eg leukemia.For a layman, yes WBC says about immunity.\nYou want me to give more details??

The first number, systolic blood pressure, measures the maximum pressure exerted as the heart contracts. This means that when the heart squeezes blood into your arteries, how much pressure gets pushed against the walls of the arteries.\n\nThe lower number indicates diastolic pressure, a measurement taken between beats, when the heart is at rest. This means that while there is no blood being forced into the artery, the amount of the pressure against the artery walls is measured.\n\nHigh blood pressure means that the force exerted on the walls of your arteries is too great. Your heart is working harder, and your arteries are stressed too much.\n\nAccording to high blood pressure guidelines from the American Heart Association (AHA), numbers under 140/90 and over 90/60 are generally considered normal in adults.

Do not eat or drink anything except water for 9 to 12 hours before having your blood drawn. Usually, you are allowed to take your medicines with water the morning of the test. Fasting is not always necessary, but it may be recommended. \nDo not eat high-fat foods the night before the test. \nDo not drink alcohol or exercise strenuously before the test.

Yours is a good question.\n\nUnfortunately, to answer it one would need to know more about your general health: information obtained through a complete physical exam, such as:\n\nBody weight, resting pulse, resting blood pressure, etc.\nAny underlying diseases.\nWhat medications if any you are currently taking.\nWhat your baseline EKG looks like.\n\nThe list is quite long, frankly.\n\nI would suggest that you ignore any answers on this web site that give you a specific number.  At this point without the above information, any such suggestions would be dangerous.\n\nMake an appointment an see a doctor you trust, be as honest as you can about your medical history and allow him or her to perform a complete physical examination.  \n\nYou will have your answer.

Your depth of breathing and rate of breathing is adjusted by your body to keep your arterial blood oxygen saturation level about 95+% (this can be checked with a simple oximeter) and the arterial carbon dioxide at 40 mm Hg (this usually requires an arterial blood sample to check).

With a routine blood test doctor checking:\n\n1.CBC (Complete blood count)\nThis is a routine test to determine the number of red blood cells, white blood cells, and platelets in your blood.   Hematocrit and hemoglobin\n2.Coagulation tests\nPT (Prothrombin time)\nPTT (Partial thromboplastin time)\nINR (International normalized ratio)\nThese tests measure how quickly your blood clots. \n3.Blood chemistry tests\nThese tests measure the levels of normal chemical substances in your blood.  \n4.Blood lipid tests\nCholesterol, total lipids, HDL, and LDL\nElevated cholesterol (particularly "bad" cholesterol, or LDL) is a risk factor for heart disease and stroke.\nThat's in brief
