Advice 1: Could a common blood test to determine the presence of marijuana

Marijuana, cannabis, "grass", "pot", "dope", "marivanna", "plan" is a mild drug, non-addictive, attribute, anecdotes about the students and joke about Holland. Although the effect of the drug visible to the naked eye, not every analysis can establish the fact of its use.
Could a common blood test to determine the presence of marijuana
By analogy with alcohol, marijuana causes relaxation and a feeling of mild euphoria: responsible cannabinoids - the psychoactive substance found in the leaves and flowers of the plant. Intermittent pleasant effects of Smoking "grass", such as relaxation and improved mood, kompensiruet inhibited reaction and the change in perception that could interfere with driving, work and many other actions that require concentration. The human body, although is not a physiological dependence, continues to get rid of the effects of drinking up to three to four weeks after Smoking marijuana, especially if the drug enters the body regularly.

Parents who care about the health of their children-teenagers and suspecting them to use "grass", often ask the question of whether the General analysis of blood to determine the presence of marijuana. An unequivocal answer to this question is no. In technology the General analysis of blood does not include techniques that allow to find traces of the drug. But there are tests for marijuana use, allowing a high degree of certainty to the result and to establish the fact of drug administration.

To identify the drug in the human body requires special study the material using saliva, urine or blood, and the blood test has a high accuracy and gives a result within a few months after the last session of Smoking. The doctor produces venous blood and conducts tests to detect antibodies produced by the body resulting from the consumption of the drug. Reaction to marijuana is individual and depends not only on the frequency of Smoking, but also from dosage, so the term antibody production is different and ranges from three to four weeks to three or four months.

Other tests - saliva and urine - is designed to search for "hot pursuit", as the saliva traces of marijuana persist up to twelve hours and in the urine from three to four days to weeks in the case of regular Smoking. At the core of these studies lies immunogeneticheskie analysis - specific chemical reaction, expressed in the change in color strips-testers. The higher the cannabinoid content, the brighter and clearer will be the result, but even in the case of a slight presence of breakdown products of marijuana test will give a positive response.

Any of the modern test procedures gives at least 90% guarantees results if used at the appropriate time.

Advice 2: Preparation for blood test

Currently, preparation for blood test is very important before visiting the medical institution. And compliance with recommendations prior to the procedure allows you to obtain the most accurate analysis results.
Preparation for blood test

If you were any radiation tests (radiographic, ultrasonic, etc.), reflexology, massage or physiotherapy, take your time and wait 1-2 days. Refrain from Smoking one hour before the tests. Note also that a blood test should be in the same medical facility. So all results will be tallied on a single performance.
Preparation for blood test also includes certain requirements in respect of the supply. Experts recommend a blood test to take on an empty stomach (after the last meal should take at least 8 hours). You can drink a small amount of water (just water, tea or coffee will already be irrelevant). In the determination of lipoproteins, cholesterol donate blood should after only 12-14 hours after a meal. And to correctly determine the level of uric acid, it is recommended to follow a special diet: eliminate from the diet purine-rich foods – liver, kidney, fish, tea and coffee.
Strictly on an empty stomach to donate blood, that is after 15 or more hours after a meal, it is recommended that upon receipt of the biochemical parameters (cholesterol, VLDL, LDL, HDL, triglycerides, etc.). While preparing for a General blood test involves following the same guidelines.
Women of reproductive age in preparation for the blood test, you also need to consider some physiological factors, including phase of the menstrual cycle. The phase cycle is necessary to specify before taking the blood test for sex hormones. This analysis should take place on certain days of the cycle: 3-5 days LH, FSH; 5-7 - estradiol; 7-9 — testosterone; 21-23 - prolactin. Pregnant women must inform the doctor the current term.
Donate blood at rest. If you hurry into the treatment room, sit down and relax for 20-30 minutes. Make sure that the doctor uses disposable needles, and testing takes place in sterile conditions. Those who can't stand the sight or smell of blood, it is recommended to relax and close my eyes. Do not RUB or pinch the injection site. Rather lightly applied with a cotton swab and hold it for 3-5 minutes. With the appearance of a bruise apply a small amount of iodine around the site of injection.
