prescription requirements for any given site before beginning field data collection, since gathering too much non-relevant information can be almost as costly as repeated field trips to gather additional information. The legal SP soil description requirements vary according to geographic area, proximity to a community watershed, and terrain. For areas where ground-based harvest systems are proposed, the most important data to be collected is the soil information necessary to complete the legally required soil disturbance hazard ratings. It can take a few days to get the results when a doctor’s office orders the test from an outside lab.SIL411, Prescriptions Field Methods Book SIL411, Prescriptions Field Methods BookĬorrect soil identification and description is critical for an effective SP. Hospitals administering the test for emergencies or people about to undergo surgery often get the results almost immediately. The amount of time it takes to get the results varies. Most people find that the test is only a brief inconvenience and a source of mild discomfort. People with bleeding disorders should tell their doctor about any history of bleeding issues. The test is safe, and complications are rare. Some people may develop a small mark or bruise.Ī technician will put the blood sample into a machine that counts the number of platelets and produces a report of the findings. Taking slow deep breaths is usually enough to calm these feelings. Occasionally, some people may feel queasy or light-headed while the blood is drawn or shortly after. Obtaining a sample of blood from a vein takes a few minutes and generally causes only minimal discomfort. The test involves drawing blood from a vein in the arm or hand. A platelet count that is lower than it once was or on the lower end of normal may not be a cause for concern in an older adult - especially if there are no other symptoms. Platelet count tends to decline with age. Chronic bleeding: Any disorder that causes ongoing uncontrolled bleeding, such as stomach ulcers, can deplete platelets.Cirrhosis: Liver cirrhosis, often due to excessive drinking, can reduce platelet count.Poisoning: Exposure to some pesticides can damage platelets.Chemotherapy: Chemotherapy harms existing tissue and cancer cells, making it difficult for the body to produce platelets.Autoimmune disorders: Autoimmune diseases such as lupus and Crohn’s disease lower platelet count by causing the body to attack its tissue.Infection: A bacterial infection, especially the blood infection called sepsis, can reduce platelet count.Anemia: A type of anemia called aplastic anemia reduces the number of all kinds of blood cells, including platelets.Lymphoma and leukemia are common culprits. Cancer: Cancer that has spread to the bone marrow can harm the body’s ability to make new platelets.Medication: Drugs, such as aspirin, H2-blockers, quinidine, antibiotics containing sulfa, and some diuretics may lower platelet count.Viruses: Viruses such as mononucleosis, HIV, AIDS, measles, and hepatitis may deplete platelets.Splenectomy: Removal of the spleen can cause a temporary increase in platelets.Ĭommon causes of low platelet volume include:.Infections: Some infections, such as tuberculosis, can cause high platelets.A person will have other symptoms in most cases. Inflammatory disorders: Diseases that cause an inflammatory immune response, such as rheumatoid arthritis or inflammatory bowel disease (IBD), can increase platelet count.Further blood testing can detect most forms of anemia. Anemia: People with iron deficiency or hemolytic anemia may have high platelets.Additional blood testing, imaging scans, or a biopsy can test for cancer. Cancer: Lung, stomach, breast, and ovarian cancers, as well as lymphoma, can cause high platelet counts.If a person’s platelet count remains high, chronic medical conditions may be responsible. intense physical activity or exertion, such as from running a marathon. ![]() recovering from excessive drinking or vitamin B12 deficiency.recovering from blood loss after surgery.Some common reasons for high platelet levels include: A doctor may order a retest a few days or weeks later if this happens. ![]() ![]() Some temporary conditions can cause a higher than normal platelet count. These include acute and chronic medical conditions and age. Several factors can cause a person’s platelet levels to change.
