Platelet Count Test

Platelet Count Test

also known as: Platelets, Thrombocyte Count

About: Platelet counts are done to know the number of platelets circulating in the blood of a person. Platelet count is a part of complete blood picture. Platelets are also known as thrombocytes and are fragments of cells and play a major role in the stoppage of bleeding. The normal range varies between 2 lakhs and 4 lakhs. The platelet count test is not done especially but in the same way as that of the blood test done for the count of any other blood cells. Platelet count is usually performed along with platelet function test as it helps to know both the number and functioning of the platelets at once.

Preparation: The patient should be instructed about the procedure of the test and asked to cooperate as there may be a slight pain while drawing blood. It will be easy to draw blood if the patient will be wearing a sleeveless dress or a half sleeve dress. A full sleeve dress whose sleeves can be easily rolled up is also fine. The arm should be held straight and not moved while drawing blood from the vein.

This test is performed to know the platelet count. This test is usually performed in case of easy bruising, petechiae, easy bleeding, delayed clotting of blood, purpura, etc. The Decrease in platelet count is known as thrombocytopenia. This is observed in case of dengue fever, zika virus infection, hypersplenism, Gaucher’s disease, few snake bites, antiphospholipid syndrome, Alport syndrome, etc. Excessive bleeding or delayed clotting also occurs due to the decrease in clotting factors. Therefore platelet count helps to eliminate platelet causes of increased bleeding favoring further investigations for the diagnosis of clotting factor causes.

Procedure: Usually, a very small amount of blood is sufficient to estimate the number of platelets but as it is done along with other blood tests 5-10 ml of blood is withdrawn. A cotton pad dipped in alcohol or spirit is used to make skin at the site of piercing sterile by cleaning. The arm is held straight and a venipuncture needle is passed through the skin into the vein at the cubital fossa most commonly. The Vein which is easily visible superficially is usually selected. Blood is withdrawn and emptied into a container. The container is sealed and the name of the patient is written on it. This sample is sent to the research laboratory for investigation. The plate count is done manually under the microscope or the sample of blood is put in an automated cell counter to get the results.

LimitationsClumping may cause false low count.1 Platelet satellitism around neutrophils will cause a pseudothrombocytopenia. RBC or WBC fragments including fragmented fragile leukemic cells and neutrophil pseudoplatelets2 may cause falsely elevated counts.

Ayurveda,
Is it good to take Patanjali Mukta Vati for high BP. Is it recommended for long term.
Ayurveda provides a holistic way of treatment. One should address other symptoms along with hypertension. Doctor should suggest diet lifestyle modifications if needed to a patient. This will eliminate cause for the disease. Further, Ayurveda advocates a personalized treatment. Though Mukta Vati is a formulation designed for the most common condition, it will not equally effective for all the patients. It may be more useful in certain disease conditions and in certain patients. Patient should leave choice of drug and overall treatment on Ayurveda expert. Otherwise if did not get result from Mukta vati you will start blaming Ayurveda. Accept Ayurveda to its fullest, not partially; if you expect sustainable results.

These Sexual Mistakes Compromise Penis Health!

These Sexual Mistakes Compromise Penis Health!

When it comes to maintaining proper penis health, most men have a very good idea of what to do. They know all the basics of penis care, from taking care to wash properly to regularly inspecting the manhood to applying a high-quality penis health crème. But in the heat of the moment, when sexual fun is getting hot and heavy, a man might make a silly mistake. Those sexual mistakes can compromise penis health in a serious way.

Not sure what sexual mistakes might be a problem? Here's a list of the biggest issues a man might find himself doing when things are hot - and might regret when things cool off.

1. That lube isn't really lube. A man who is getting it on but suddenly realizes the need for lube might reach for whatever is handy, assuming a bottle of lube is not available - and sometimes that means he will try to use anything from shampoo or conditioner to lotion or cooking oils. Obviously these things are not meant for use as a sexual lubricant, and can lead to dry and cracked skin, irritation and more. Using lube designed specifically for the sexual purpose is always recommended.

2. The condom is too small. Though it is very important to always wrap it up before sexual activity, the wrapping itself might sometimes be the issue. Using a condom that is too small might lead to a little irritation in the heat of the moment, but a man can often ignore that for pursuit of pleasure. The aftermath is when things get rough, as the penis can develop small cuts, tears or even blisters from the use of a condom that is too tight. It pays to test out a variety of condoms to find the best fit.

3. There's been too much drinking. Sometimes a bit of inebriation can be a good thing, as it lowers inhibitions and can help both partners relax before the main event. But too much drinking can lead to serious problems, including trouble with getting it up or issues with stamina. But too much alcohol consumption can lead to even worse things, such as forgetting to use a condom or even suffering memory loss that leaves a man wondering just what happened the night before. Avoiding this is simple: don't drink too much before a bedtime romp.

4. Cleaning up is not a priority. There are plenty of bodily fluids sliding around during sexual activity, and much of that understandably winds up on a man's penis. From the natural lubrication that occurs during sex to the traces of spermicide in the condom, there can be several substances that linger. A man who doesn't clean off his penis after sex is asking for trouble, as those fluids can dry on the penis skin, leading to itching, irritation and redness, as well as a potential penis rash.

A man who pays attention to good penis care should always remember that caring for the penis extends to those moments when things are hot and heavy. Not only should a man be fully prepared for any sexual encounter, he should also be sure to take care to clean up well afterward. Maintaining good health should also include regular use of a high-quality penis health crème (health professionals recommend Man 1 Man Oil, which is clinically proven mild and safe for skin). Look for a crème that includes a multitude of vitamins and nutrients, such as vitamin A for odor-fighting properties, vitamin E to keep skin supple, and vitamin C to enhance sexual health. Amino acids such as L-arginine for blood vessel dilation and acetyl-L-carnitine for protection against peripheral nerve damage are also helpful. Combine it all in a Shea butter base and a man has the recipe for great penis health.

Articulation Problem!

Articulation Problem!

A child may have an articulation disorder if they are deleting sounds (e. G, saying “doic” for “dog”), substituting sounds (e. G, “dat” for “cat”), addingsounds (e. G, “balue” for “blue”) or distorting sounds (e. G, “thpoon” for “spoon”). In general, there is a range of typical speech-sound development. Most children are 90% intelligible to a wider range of communication partners by the age of four. If you are concerned about your child’s speech intelligibility or articulation, it is best to seek the advice of alicensed speech-language pathologist who will conduct a formal assessment. This formal assessment will involve looking at both speech and sound production and sound error patterns or distortions.

Pain killers and Heart Attack Risks!

 

  •  Doctors have found the use of pain relievers to treat respiratory infections like cold flu may increase the risk of heart attack.
  • For the study, researchers analyzed insurance claims from taiwan's national health insurance program from 2005 to 2011 with data from roughly 10, 000 patients who were hospitalized for a heart attack.
  • The purpose of the study was to assess whether cardiac risk factors from an acute respiratory infection and the use of non-steroidal anti-inflammatory, pain relievers combine to further increase the risk of heart attack.
