You can outline the differences of serum and plasma in the several  aspects. They are both blood specimens used in laboratory testing, but each has its own characteristics.

Criteria Serum Plasma
Anticoagulant none Present
Protein present albumin , globulin albumin, globulin & fibrinogen
Rimming of specimen done not done
Standing of specimen done Not done
Revolutions per minute (RPM) 2,000-3,000 2,000 – 3,000
Time of centrifugation 5 – 10 minutes 5-10 minutes
Supernatant fluid Supernatant fluid when clotted blood is centrifuged. Supernatant fluid when unclotted blood is centrifuged.

These are major differences of serum from plasma. What is important is when to know what specimen is ideal for a particular laboratory blood test.

If you are hypertensive, then you should know what to eat and what not to. The ideal food for hypertensive patients are the following.

Low salt foods

Salt increases blood pressure, so you should lessen your salt intake. Salt can come not only from table salt but also from most preserved foods. Opt for fresh foods instead of these types of foods.  Saltine crackers and some oatmeal brands are also rich in salt. Read the labels and ascertain that the salt content is low before eating it.

Low fat foods

Hypertension can result from high lipids or fats, so these types of foodstuffs should be avoided.  Fat can come from meat fat, like pork and chicken fat.

Dairy products

Most dairy products are rich in triglycerides and cholesterol which are predisposing factors in increasing the likelihood of hypertension.

Foods for hypertensive patients include fruits and vegetables because these foodstuffs are low in calories and are fat free. Vegetable oil and fish oil are healthy fats so they can be taken in. Knowing what food to eat and what not to, is a big factor in controlling your hypertension. You should therefore know the ideal foods for hypertensive patients to help you out in maintaining your health.

Bilirubin is the major bile pigment in the body.  There are crucial precautions you should observe in performing bilirubin tests because the substance can be affected by many factors. Here are precautions that are observed in the Jendrassik and Grof method and Evelyn and Malloy method.

Avoid hemolysis of blood specimen.

Bilirubin is a degradation product of Red Blood Cell or RBC, so any lysis or rupture of these blood cells will increase inaccurately the results of the bilirubin test.

Avoid exposure to light.

Biluribin is photosensitive. It is easily destroyed by light, so exposing it to natural or artificial light will erroneously decrease its laboratory results.

Maintain the correct pH.

Maintaining the correct pH or alkalinity and acidity of the test solution and reagent will ensure the reliability of results. This is vital precaution in performing bilirubin tests.

Avoid interference from proteins and foreign substances.

Protein and foreign substances will greatly affect you bilirubin tests.  Be sure to cover your solutions at all times with a rubber stopper or a parafilm. This will ensure that the results of your bilirubin tests are accurate and precise.

Meditation and its healing powers cannot be discounted. It is a powerful tool for therapeutic purposes. It was only in the 20th century that the rest of the world became truly aware of the healing values of meditation and adapted this as one of their alternative healing treatment. Researches have proven that meditation is useful if done properly under the supervision of an expert or able guide. Its healing value should not be disregarded and should be researched on continuously.

But first what is meditation? What are the types of meditation?

Meditation is a mind-body intervention that has the purpose of creating a restful state in the person thereby allowing his body to heal and enhancing the proper occurrence of biochemical processes in his body. This would relieve the person of stress and contributes to his well being.

There are four general methods of meditation:

1. Transcendental meditation (TM). This is usually done with the appropriate mantra for the person. The common position for this and the other three methods is a lotus position, but you can adapt any position that you feel most comfortable with, as long as the back is straight and you could maintain a good posture. The eyes should be closed to attain more focus and concentration.

2. Respiratory One Method (ROM) by Herbert Benson This concentrates on the word “one” as you go on with the breathing exercise. A word can be combined to act as the mantra.

3. Clinically Standardized Meditation (CSM) This is considered the easiest by beginners to perform because the person is allowed leeway to select the mantra and not to follow the structured ones.

4. Mindfulness Meditation (MM) This method does not encourage the person to maintain the “blank-out” state of the mind but allows “thoughts” instead.

What exactly are the beneficial effects of meditation?

1. Although meditation is not for everyone, Dr. Robert H. Schneider, Dean College of Maharishi Vedic Medicine, Iowa who leads the research on transcendental meditation’s effect on hypertension and cardiovascular diseases said that: “those individuals who practiced TM had regression of left ventricular mass and improvements in the function of their heart or essentially a reversal of the damage to the heart caused by hypertension. ” (From: Mosby’s Complementary and Alternative Medicine by: Freeman Lawlis). He went on to say that health care professionals could work in collaboration with a TM class for patients who have elevated blood pressures and those with heart diseases.

2. The level of anxiety is significantly reduced and thereby there is decreased heart rate, respiration rates (RR), cortisol and lactate concentrations (substances which are elevated during stress).

3. Meditation, (because of the state of relaxation that you undergo) also desensitizes the mind of anxious thoughts and fears and therefore promotes balance in the body and the subsequent proper functioning of the vital organs.

4. The regular rhythm obtained from the meditation creates a balance between the right and left hemispheres of the brain. It is believed that when the left brain’s workload is lessened, negative thoughts are also decreased.

5. It reduces health care cost because meditation decreases the propensity to diseases caused by a stressful lifestyle; like late nights out, improper diet, and lack of exercise.

6. When undertaken on a regular basis, it could also be utilized to treat mood disorders. The patient should be receptive; however, to the concentration technique needed in the procedure so that the beneficial calming effects would be maximized.

7. It is also effective in decreasing the attacks for asthma, psoriasis and menopausal syndromes.

8. It is useful as a complementary treatment for addictive behaviors. Persons who undergo meditation had decreased drug cravings, less propensity for drug usage, due to the calming effects of meditation.

Up to this day, researches and controlled trials are still being conducted to determine the healing effects of meditation on humans. It would be wise to realize that meditation is a procedure that should be utilized according to each individual’s needs and preferences. As always, an expert or doctor should be consulted before initiating treatment with meditation.
