Blood Draw Requirements

If a person has been exposed to blood through unhealthy skin, mucous membranes or a puncture wound, complete an incident report as described in the WHO Best Practices Toolkit for injections and related procedures. For the transportation of blood samples outside a hospital, equip the transport vehicle with a blood spill kit. Appendix H provides more information on how to deal with blood spills. No one is eagerly waiting for blood to be drawn, but the procedure is usually short and uneventful. Most people get in and out of the lab room in less than 15 minutes. The phlebotomist begins by gently pressing his fingers against your skin to find the best vein. Then he or she puts on gloves, cleans the area with an alcohol swab, ties a tourniquet around your arm to increase blood flow, asks you to make a fist, and inserts the needle. Fasting for a blood test means avoiding all foods and drinks (except water) for 8 to 12 hours before the test. Drink plenty of water and take your medication as usual. Note that a small number of tests have stricter requirements, such as the H. pylori breath test, in which nothing, including water, is consumed an hour before the test.

A common basis for challenging blood test results is to show that the police or testing facility did not follow the proper rules and procedures for blood tests. This includes displaying the correct chain of command, sterilization, anti-contamination measures, sample identification and recording, and sample speed. If proper procedures have not been followed, the blood test may be inaccurate and should not be used as evidence against the accused. If your doctor told you to fast before a blood test, it means you shouldn`t eat or drink anything other than water for several hours before your test. When you eat and drink normally, these foods and drinks are absorbed into your bloodstream. This could affect the results of certain types of blood tests. Make sure that the indications for blood collection are clearly defined, either in a written protocol or in documented instructions (e.g. in laboratory form). But you can drink water. It is actually good to drink water before a blood test. It helps keep more fluid in your veins, which can make it easier to draw blood.

It is acceptable, but not ideal, to take blood samples when, for the first time, a venous device is inserted into the apartment, before the cannula is connected to the intravenous fluids. However, these blood and breath tests are not always accurate and a false test result should not be the basis for a conviction. Talk to your Virginia DUI defense attorney about your DUI charges and how to challenge the DUI blood test results. Under Virginia`s Implied Consent Act, drivers are deemed to have given consent to post-arrest chemical testing, including blood tests. In accordance with Virginia Code § 18.2-268.2, any person driving a vehicle in the Commonwealth of Virginia is deemed to have consented to blood samples and/or breath samples being taken for chemical testing to determine the alcohol and/or drug content of their blood within three hours of the alleged offense. If law enforcement suspects that the driver is affected by drugs or the combination of alcohol and drugs, they usually take a blood sample instead of a breath sample. There are a number of reasons why police may suspect that the driver is under the influence of drugs (as opposed to alcohol), including tourniquets are a potential source of methicillin-resistant Staphylococcus aureus (MRSA), with up to 25% of tourniquets contaminated by poor hand hygiene on the part of the phlebotomist or reuse of contaminated tourniquets (35). In addition, reusable finger prick devices and related point-of-care screening devices (e.g., glucometers) contaminated with blood have been associated with hepatitis B outbreaks (4, 5 and 36). * If we explain that Laboratory Alliance cannot use microtainer or finger stick/heel blood, the reason is not in the amount of blood. Some laboratory tests may not use capillary blood because there are slight differences in the composition of capillary blood compared to venous blood.

These differences would affect the testing methodology and cause inaccuracies if performed with capillary blood. ** Newborns with elevated HCTs need more blood than indicated You will need a lab prescription from your provider to have your blood drawn. If you are not sure if you have an order on file, call our office and we will take a look. If you would like your supplier to order blood tests, we recommend that you make an appointment so that you can discuss your concerns and create a series of tests tailored to your needs. Make sure the blood sample is done privately and cleanly. Tip: Chat helps. A medical phlebotomist makes it a point of honor to engage you in a conversation to help you relax so that the needle prick is a little less painful. Chat with your phlebotomist and distract yourself from the draw! No. Juice, coffee, sodas and other beverages can enter your bloodstream and affect your results. In addition, you should not: Pull the blood collection tubes in the right order to avoid cross-contamination of additives between the tubes. Since color coding and tube additives may vary, consult the recommendations with local laboratories. By way of illustration, Table 2.3 shows the revised and simplified recommended collection order for vacuum tubes or syringes and needles, based on the consensus of the U.S.

National Committee Clinical Laboratory Standard in 2003 (43). A blood test in a case of DUI is much more complete than a breath test. Breath tests only check for the presence of alcohol in the body, usually based on the blood alcohol concentration (BAC). For most drivers in Virginia, a blood alcohol level of 0.08% or higher is in itself a violation of Commonwealth drunkenness laws. If a driver is stopped and unable to perform a breath test, they may be required to undergo a blood test. A driver may not be able to perform a breath test if they cannot give the full breath required for the test device, if they are unconscious, or if they cannot follow the instructions. Clear information – written or oral – should be available to any patient undergoing phlebotomy. Appendix F contains an example of text explaining the procedure for collecting blood for a patient. Tip: Know your limits. If you have fainted in the past or have a phobia of needles, inform the phlebotomist immediately. They can position you in such a way that you are less likely to faint, hold their needles out of your line of sight, or use the right words to calm you down during the draw.

The information in this section supports the information in the remainder of Part II for specific situations. Chapter 4 also contains information on the blood collection procedure indicated in section 2.2 below, but focuses on the collection of blood from donors. One Medical Group provides walk-in lab services on-site at most of our offices across the country. This means that you can take a blood test right after a visit or at will during the week. Our opening hours vary by location, so check our website or call ahead to make sure the lab is open when you plan to arrive. Tip: Get a head start on hydration. Drink extra water from the day before your blood test to make sure you are sufficiently hydrated on the day of collection. Your provider has just ordered blood tests and you are preparing to do so. Here`s what you need to know in advance to ensure a convenient and easy draw. In hospitalized patients, do not draw blood from an existing peripheral venous access site, as this may lead to incorrect results. Hemolysis, contamination, and the presence of intravenous fluid and medication may alter the results (39). Nurses and doctors can access central venous lines for samples that follow protocols.

However, samples from the central lines carry a risk of contamination or incorrect laboratory test results. One. Upon receipt of a blood sample submitted to the Division for analysis in accordance with § 18.2-268.6, the Division shall have it examined for its alcohol or drug content or for its alcohol and drug content, and the Director shall issue a certificate of analysis indicating the name of the accused; the date, time and date, time and time the blood sample was received and examined; a statement that the seal of the vial has not been damaged or otherwise altered; a statement that the container and vial were provided or approved by the Department and that the vial was a vial with the completed return certificate; and an indication of the alcohol or drug content of the sample or the alcohol and drug content. The Director must take the certificate of return of the vial and either attach it to the certificate of analysis and indicate in the certificate of analysis that it has been removed and attached in this way, or (ii) scan it electronically in the ministry`s laboratory information management system and place the original certificate of declaration in its specific file. The certificate of analysis and the certificate of withdrawal must be returned to the clerk of the court before which the indictment is heard or transmitted electronically. DUI blood tests look for alcohol as well as a number of other substances. These tests primarily look for drugs or chemical identifiers, or certain narcotics, prescription drugs, or other substances that can impair a driver`s ability to drive a vehicle safely.
