Why do I need this assessment?

Laboratory assessments may be done for many reasons. Assessments are performed for routine health screenings or if a disease or toxicity is suspected. Lab assessments may be used to determine if a medical condition is improving or worsening. Lab assessments may also be used to measure the success or failure of a medication or treatment plan. Lab assessments may be ordered for professional or legal reasons. The following is a possible reason why this assessment may be done:

* Candidemia

* Systemic fungal infection

When and how often should I have this assessment?

When and how often laboratory assessments are done may depend on many factors. The timing of laboratory assessments may rely on the results or completion of other assessments, procedures, or treatments. Lab assessments may be performed immediately in an emergency, or assessments may be delayed as a condition is treated or monitored. A assessment may be suggested or become necessary when certain signs or symptoms appear.

Due to changes in the way your body naturally functions through the course of a day, lab assessments may need to be performed at a certain time of day. If you have prepared for a assessment by changing your food or fluid intake, lab assessments may be timed in accordance with those changes. Timing of assessments may be based on increased and decreased levels of medications, drugs or other substances in the body.


The age or gender of the person being assessmented may affect when and how often a lab assessment is required. Chronic or progressive conditions may need ongoing monitoring through the use of lab assessments. Conditions that worsen and improve may also need frequent monitoring. Certain assessments may be repeated to obtain a series of results, or assessments may need to be repeated to confirm or disprove results. Timing and frequency of lab assessments may vary if they are performed for professional or legal reasons.


How should I get ready for the assessment?

Before having blood collected, tell the person drawing your blood if you are allergic to latex. Tell the healthcare worker if you have a medical condition or are using a medication or supplement that causes excessive bleeding. Also tell the healthcare worker if you have felt nauseated, lightheaded, or have fainted while having blood drawn in the past.

How is the assessment done?

When a blood sample from a vein is needed, a vein in your arm is usually selected. A tourniquet (large rubber strap) may be secured above the vein. The skin over the vein will be cleaned, and a needle will be inserted. You will be asked to hold very still while your blood is collected. Blood will be collected into one or more tubes, and the tourniquet will be removed. When enough blood has been collected, the healthcare worker will take the needle out.


How will the assessment feel?

The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the assessment. Inform the person doing the assessment if you feel that you cannot continue with the assessment.

During a blood draw, you may feel mild discomfort at the location where the blood sample is being collected.


What should I do after the assessment?

After a blood sample is collected from your vein, a bandage, cotton ball, or gauze may be placed on the area where the needle was inserted. You may be asked to apply pressure to the area. Avoid strenuous exercise immediately after your blood draw. Contact your healthcare worker if you feel pain or see redness, swelling, or discharge from the puncture site.

What are the risks?

Blood: During a blood draw, a hematoma (blood-filled bump under the skin) or slight bleeding from the puncture site may occur. After a blood draw, a bruise or infection may occur at the puncture site. The person doing this assessment may need to perform it more than once. Talk to your healthcare worker if you have any concerns about the risks of this assessment.


What are normal results for this assessment?

Laboratory assessment results may vary depending on your age, gender, health history, the method used for the assessment, and many other factors. If your results are different from the results suggested below, this may not mean that you have a disease. Contact your healthcare worker if you have any questions. The following is considered to be a normal result for this assessment:

Adults and Children: Negative or No Growth

What follow up should I do after this assessment?

Ask your healthcare worker how you will be informed of the assessment results. You may be asked to call for results, schedule an appointment to discuss results, or notified of results by mail. Follow up care varies depending on many factors related to your assessment. Sometimes there is no follow up after you have been notified of assessment results. At other times follow up may be suggested or necessary. Some examples of follow up care include changes to medication or treatment plans, referral to a specialist, more or less frequent monitoring, and additional assessments or procedures. Talk with your healthcare worker about any concerns or questions you have regarding follow up care or instructions.

It may take up to 4 weeks to receive the results of this assessment [1].
