The Bodybuilder Guide to Blood Work

I dare guess what happens if you, a weightlifter, go to the doctor to get a doctor. I'll bet you'll almost always get a follow-up call from your doctor informing you that one or more of your lab values ​​are disabled and you need to retest them.

The doc says something like, "I'm a bit worried about your (fill-in-the-blank) level, it's a little high, to be honest, we only see those scores in end-stage cancer patients, people A moment from a deadly cardiovascular event, or some poor bastard who's been knocked down by an ox. "

Okay, he probably does not say anything scary, but probably your paranoid mind will hear it anyway. Regardless, you will need to undergo another lab test and there is a risk that the re-tested laboratory values ​​will be about the same, and your worried doctor will want to pathologize the pathological blood test that you showed.

Maybe he or she will do this Carry out the bill with some additional tests, all of which will be negative, but there is also the possibility that you will receive from the doctor a drug that you feel have been lobotomized and you have to spend your days with a slobbering bucket your neck.

I'm here to tell you that you're probably not sick. You are just a lifter and your body chemistry is a little different from the other animals. Here's a little reference book that you can unpack in the future if you or your doctor are wondering about your inhuman blood levels.

Possible Pitfalls Before Blood Collection

Sometimes what happens before you get blood off If you lose your blood, you can get crazy results, all because you lift weights and have a bodybuilder mentality.

  Blood Pressure

Blood Pressure

There's a good chance your arm circumference is too big A normal blood pressure cuff, and your poor arm will feel like a sumo wrestler accidentally sitting on it while sitting on a yoga mat were stretched.

The overpressure causes your systolic blood pressure to rise (the first number in the BP reading). A 2009 bodybuilder study (Fonseca-Reyes) found that the average amount is 8 points higher and that this might be good enough to convince your doctor to put you on a high blood pressure medication, which you're probably constantly on sleepy, grumpy. and dopey.

To prevent this, speak the person taking your BP in the closet to blow off the dust from the big boy's cuff. Likewise, it is your responsibility to do the following to ensure that you get reasonably accurate values:

  • Avoid stimulation. Do not drink coffee, do not exercise, and do not smoke within 30 minutes of the test.
  • Piss. You must empty your bladder before you sit down.
  • Relax. You must be quiet in the room for at least 5 minutes before attempting to take your blood pressure. Then stay calm while it is taken.
  • Put the right way. You must sit on a normal chair with your back and feet flat on the floor (do not cross your legs).
  • Position your arm properly. Your upper arm must be supported in the middle of the heart, and your elbow must be bent at a 45-degree angle.
  • If possible, receive two careful measurements on at least two separate occasions.

You might not believe being a bodybuilder could screw up the blood, but it can. It is potassium, a mineral that is essential for human life. It acts as an electrolyte and facilitates the movement of the muscles, including those that control your breathing and your heartbeat.

Too much potassium in the blood – a condition known as hyperkalemia – may indicate a kidney failure and an impending heart attack that could cause your doctor to have the vapors when he or she sees your blood tests.

The thing is, elevators, especially bodybuilders, often test fake water for alarming levels of potassium and the reason for that is particularly stupid. When normal people lose blood, they briefly clench their fists to make the vein more visible to the phlebotomist. Once the vein is located and the needle is inserted, immediately relax your fist.

Not so with many bodybuilders. They do not clench their fists, they roll their fingers into a rage ball to admire the huge, pulsating veins that run their arms like an oil pipeline through a South Dakota prairie.

And then fixed by their own gifts, they do not relax their fist, if they should; they just keep staring at these beautiful veins. As a result, thousands of red blood cells burst during blood collection, losing all of their potassium reserves. The resulting crooked lab results in a heavy phone call from the ordering nurse's nurse prompting you to come in immediately before death.

To avoid this, do not be overwhelmed by your talent – relax your fist immediately afterwards Tech introduces the needle.

  Blood Testing Results

Crazy Blood Work Numbers

Their crazy weight lifts, trains, whips up protein, complements Takin's lifestyle leaves a diagnostic chemtrail, but when most doctors try to make you feel more comfortable than Warning signs in place of the usual side effects of your physical lifestyle wrong.

Here are the most common blood tests that are generally confused with strength athletes and athletes:


alananine transaminase (ALT) and aspartate transaminase (AST) are enzymes that, when elevated, are , Can indicate liver damage. Unfortunately, your doctor probably does not know that even a 15-minute treadmill on the treadmill can significantly increase the two transaminases.

An old study from 1962 (Fowler) showed that even a short 8K run can increase ALT and AST values ​​by 150%. This just means that during the run, muscle damage has been inflicted on runners, and when stupid runners come up, imagine the damage your training will cause.

As an interesting aside, one researcher suggested this (Pertusi, 2007). Elevated ALT and AST levels are the reasons why liver damage from the use of anabolic steroids seems so common. The suspected liver damage (presumed by the elevated ALT and AST levels) was indeed physical and temporary, as opposed to steroid-induced and long-term. Nevertheless, it is believed that steroids cause much more damage to the liver than they are likely to do.

If one or both of these transaminase tests are high, take a week off the hard training and have your blood tested again. [19659031] BUN

Blood Urea Nitrogen (BUN) is a measure of urea levels in the blood and may indicate a kidney failure. However, a high-protein diet in combination with hard training increases protein turnover, resulting in increased urea production and increased BUN levels.

Increased BUN through protein and workouts is no cause for concern, but the doctor must do this. Remember your lifestyle so he does not freak out.

Creatine kinase

Elevated levels of this enzyme often indicate myocardial infarction, kidney damage, muscular dystrophy and rhabdomyolysis. Fortunately, this probably just means that you trained hard the day before your blood test. If you hit your muscles hard, the creatine kinase level can increase 100-fold.

In fact, there are some thoughtful researchers who are pushing for the lab values ​​of lifters and athletes to be revised. They suggest that "normal" levels are boosted by the current

Until this happens, either expect a worried phone call from your doctor after taking a blood sample, or do not clear the day before you have made a purchase.


This compound is a by-product of creatine phosphate, the chemical used in muscle contraction. High levels sometimes indicate urinary tract infections, decreased renal flow and acute tubular necrosis (kidney damage).

But do you know what else increases creatinine levels? Taking creatine or taking large quantities of beef or other high-creatine meat. This also explains why some creatine naysayers insist that creatine causes kidney damage. But they miss something.

Yes, creatinine levels are used to assess kidney function, but when doctors find creatinine levels high in people who use creatine, they believe creatine has actually been damaged kidneys and creatinine levels have increased, although the increase actually occurred only because part of it was converted to creatinine.


The glomerular filtration rate is used to test how well the kidneys are working. However, high protein intake may increase GFR, in particular due to the use of protein powders, as well as creatine supplementation. In your case, that's no cause for concern, but your doctor needs to know about your lifestyle.


This test measures the percentage of your blood that consists of red blood cells. If it is too high, it may mean a risk of stroke. Too many red blood cells, such as cars on a highway, can lead to congestion and congestion. Not good.

Unfortunately, anabolic steroids and even testosterone replacement therapy can raise hematocrit to alarmingly high levels. Normal values ​​for men are between 45% and 52%, while women should test at 37% to 48%. If your level is above 52% (in men) or 48% (in women), you will need to take some blood (to lower the risk of stroke immediately) and adjust your androgen dose accordingly.

Total Protein

This test measures the total amount of albumin and globulin in the body. Albumins indicate liver function, while the body uses globulins to make antibodies. Increased albumin levels alert your doctor to the possibility of liver disease, inflammatory disease, or malnutrition, while increased globulin levels can be caused by elevated cholesterol, iron deficiency, or inflammatory disease in general.

Total Proteins May Also Be Elevated People using anabolic steroids, growth hormones or insulin should tell your doctor about extracurricular injections, even if it means that you are lecturing on the dangers of steroids (he does not agree much about insulin)

Total Testosterone

This is the most confusing of all blood tests, and most doctors will not care if you do it test high or low. To be honest, it does not matter how high your total T is, because testing for total testosterone alone is pretty ridiculous.

Your body only cares about "free" testosterone and albumin-bound testosterone is loosely bound but may be available to do all the good that T does. Together, they are a "bioavailable" testosterone.

However, the determination of free and bioavailable testosterone is problematic. They could only test for free testosterone, but the tests are terribly unreliable. A study by the Endocrine Society of America found that free testosterone levels in the same sample may vary by a factor of five. You could test the same sample several times and get different readings.

You could also test the SHBG level and theoretically get an idea of ​​your hormone status, but SHBG is a nasty bastard. They may be low in SHBG and have "normal" T levels, but there is a lack of bioavailable T.

At what time of the day you lose your blood is also tricky. The current idea is that you need to have blood tests done early in the morning, unless you are an older or older bastard. It probably does not matter at this point. Younger men (those under the age of 45) have higher levels of testosterone in the morning, probably around 8:00 in the morning, reaching their low point about 12 hours later.

For older men this does not seem to help fluctuations, so they can almost always be tested before 2pm.

What you eat before you lose blood can also affect testosterone levels. Some studies have shown that high-fat meals can reduce T-levels by 15-40%. Similarly, high carbohydrate meals may decline between 10 and 30% for 3 to 8 hours. Even consuming a drink containing about 75 grams of glucose (what you would get in one of these "rockstar" energy drinks) is enough to lower the testosterone level by 47% by lowering the jaw. So it seems that testing should be fasting, but there is always the chance that fasting will also lower testosterone levels and prevent an accurate picture. It's crazy.

My best advice is this: If your total T, free T or bioavailable T or a combination of the three is low and you feel like your energy levels, libido and muscle mass you may not be up to date experiment with a testosterone-enhancing drug, or find an understanding doctor and consider a replacement for T, as I explained in The Complete Guide to T Replacement.
