Why is a blood test done before surgery? I am having cervical surgery done and it is covered by workers comp.I have to have a blood test before surgery.I currently take injesctable steroids.Will it be found in my blood test or do they even check for that?
Routine : Routine pre-operative blood tests are done to be sure that you won't run into bleeding problems. They check your platelet count, your red blood cell count, and for abnormalities in the chemical components that help your blood to clot normally. Steroids would not be picked up on these tests. I'm not sure what you mean by injectable steroids. Anti-inflammatory prescription corticosteroids will increase blood sugar levels and might show up for that reason. They can also slow healing and increase the risk of infection. Anabolic steroids, which are often used illegally to build muscle mass, can lead to other problems, not the least of which is that, because they are acquired and used illegally, they may have impurities and are of unknown dosage. You should discuss this with your doctor. He or she needs to know about any medications you're taking--legal or not--and is not going to report you to the police if you're using something illegal. ...Read moreSee 1 more doctor answer
Which test?: If you mean "glucose tolerance test", then breakfast beforehand will ruin it, as will not complying with the preparation.

I got blood work done after a carbon monoxide leak was discovered at work and came back with a 2.5 level. Is this a high level for a non-smoker?
Not high, but...: Non-smokers in non-urban, non-industrial areas are probably under 1-2%. People living in urban, industrialized areas can be a little bit higher, so 2-3% sounds ok. Smokers can be at 4-8%, approximately. However, the half-life (how long it takes for a higher level to drop in half) is about 5 hours. The 2.5% could have been there always, or could have been a decrease from a level of 5%, 5 hours ago. ...Read more
I was wondering if a normal colonoscopy is painful and is a virtual colonoscopy as accurate as a normal colonoscopy and can it detect any cancer?
Would donating blood 1-2 weeks before before having a CBC test done interfere with the results of the test?
No: There are not any routine substance tests that are performed at a physical, or check up. If you have a court appointed examination within the legal process, there may be testing required, or for hiring for some workplaces. But at this time, for a free individual maintaining their own liberties, there will not be any tests performed without your knowledge or consent. ...Read more

Just turned 50. My primary care doc did lots of blood work, a prostate exam, & sent me for a colonoscopy. Shouldn't I have a dermatologist check me?

The : The tests very well could have come back low due to you donating blood. A good idea would be to take iron or a daily multi-vitamin for 3 months then repeat the anemia panel. If you still have anemia your doctor can do a simple test of your stool to check for the presence of blood. If it is positive then you should have another colonoscopy. Best of luck. ...Read moreSee 1 more doctor answer

Investigate iron def: If an adult has anemia DUE TO IRON DEFICIENCY, the cause is almost always blood loss. In men and non-menstruating women, the blood loss is almost always from the gastrointestinal tract. If iron deficiency (not just anemia) has been well proven, and the patient does not menstruate, endoscopy is warranted no matter what the occult blood stool test shows. ...Read moreSee 1 more doctor answer
