Bottle Cultures
Additive: Nutrient Broth
Laboratory responsible for specimen testing: Microbiology

A

When a patient shows symptoms of a systemic infection or has a fever of unknown origin (FUO), a blood culture is performed to determine the presence of pathogenic or infectious microorganisms in the bloodstream. If infectious microorganisms are present, the nutrient broth will promote the rapid growth of microorganisms. Once assessed and positively identified, the infection can be controlled and treated with antibiotics.

155
Q

Sterile Bottles (BCX)
Blood culture bottles contain SPS (sodium polyanethol sulfonate). In certain situations, a Yellow Top Tube (containing SPS) may be used for bacterial and fungal blood culture.
Blood culture collection requires a strict aseptic technique. The most common cause of blood culture contamination is improper site preparation.

A

The venipuncture site is cleansed with ChloraPrep to minimize the risk of contamination.
the top of the collection bottles should be cleaned. Let the ChloraPrep solution dray, then draw the blood.

156
Q

A

Collection Method: Blood cultures are ordered in sets of two (BC x2), each set consisting of two bottles:
aerobic (with oxygen)
anaerobic (without oxygen)
These blood draws and lab tests are usually ordered STAT or as timed specimens.

157
Q

Clear Top Tube = Discard

A

A Clear Top Tube is used as a discard tube. A sample is drawn into this tube and then discarded to avoid the thrombin and other cells polluting the samples drawn into different tubes. In some clinical settings, a Red Top Tube will take the place of a Clear Top Tube as the discard tube.

158
Q

Light Blue Top Tube
Additive: Sodium Citrate - an Anticoagulant
Yields: Plasma
Laboratory responsible for specimen testing: Coagulation
Common Tests: PT, PTT, aPTT

A

Sodium citrate prevents coagulation by binding to the calcium specimen. This additive is used for coagulation studies because it preserves the coagulation factors in the specimen.
Sodium citrate is a liquid additive that requires a specific blood-to-additive ratio.
-The ratio is 9 parts blood to 1 part additive.
-The Light Blue Top Tube must be filled completely to avoid an inadequate blood-to-additive ratio. There is a line marked on the tube to ensure the proper amount.
-The sample is collected and inverted 3-4 times to mix the blood and additive properly.

159
Q

Light Blue Top Tube and Platelet-Rich Plasma (PRP)
-Platelet-rich plasma (PRP) therapy is a process where a patient’s platelets are harvested from their blood. Those platelets are then injected back into their body to accelerate healing in a particular area of concern.
-To process platelet-rich plasma (PRP) from a blood draw, the Light Blue Top Tube is used. This tube is used instead of other tubes because it contains the anticoagulant sodium citrate. Other anticoagulants do not work as well for obtaining the end process.

A

-Blood is usually drawn into two Light Blue Top Tubes to provide the required amount necessary for PRP therapy.
-The blood is centrifuged for 12 minutes. The horizontal spinning centrifuge creates the best results for harvesting PRP.
-After the blood is centrifuged, plasma is withdrawn from the Buffy coat layer via a 2-inch, 18-gauge needle and a 30 mL syringe. The buffy coat layer is the white separating layer between the red blood cells and the plasma layers.
-The harvested sample is rich with platelets, hence the name platelet-rich plasma. This specimen is then injected into an area requiring expedient healing.
-The PRP can also be mixed with freeze-dried bone to create sticky bone material that is packed into hard tissues (bone) to accelerate healing.

160
Q

Red Top Tube
Additive: None - Glass; Clot Activator - Plastic (silica)
Yields: Serum
Laboratory responsible for specimen testing: Chemistry
Common Tests: This tube is also known as a “plain vacuum tube.” It contains no additive or anticoagulant. In this tube, blood will clot naturally within 30 - 60 minutes. With clotting factors left in the blood, a Red Top Tube can be used for a serum pregnancy test.

A

A Red Top / Plain Tube is frequently used as a”discard” tube to prevent sample contamination. It is sometimes used to “clear the line” to obtain a purer sample.
-There is no need to invert this tube after sample collection.
The exception to the rule is: If the Red Top Tube is made of plastic, a clotting agent is added as plastic tubes’ sides are too slick for natural clotting to form.
-Alcohol (Ethanol or ETOH) levels can also be drawn in a Red Top Tube when testing serum.

Q

Newborns are screened for many things before released to go home from the hospital. Most screenings are done from the heel stick collection including: Cystic Fibrosis, Hypothyroidism, Galactosemia, Bilirubin, PKU, Sickle Cell, Toxoplasmosis, Brotianides Deficiency, HIV

A

-Bilirubin (light protected) is a standard test performed on babies via heel stick. When bilirubin is overproduced, this is due to the liver not breaking down and excreting red blood cells as it is supposed to do. This causes a baby to become jaundiced or yellow.
-Bilirubin is dangerous in infants since it can accumulate to toxic levels which can cause permanent brain damage and death. High bilirubin, or jaundice, becomes visible about 2-3 days after being born. If the condition is not too severe, it can go away with minimal treatment in about 1-2 weeks. The most common treatment for this is Phototherapy, o “light” therapy.

179
Q

Heel Stick
-The heel is used for dermal punctures on infants and toddlers up to two years of age areas recommended for a heel stick are the medial and lateral portions of the plantar surface of the foot.
-By drawing imaginary lines medially extending from the middle of the great toe to the heel, and then laterally from the middle of the fourth and fifth toes to the heel, the phlebotomist will know where to draw the blood.

A

-The American Academy of Pediatrics, or AAP, recommends that heel punctures not exceed 2.0mm for infants. Preemies should not exceed 0.85mm.
-Before performing a heel stick on an infant, a heel-warmer should be placed on the foot for 2-5 minutes. A heel-warmer dilates the capillaries and vessels and allows increased blood flow to that area.
1) Do not puncture deeper than 2.0mm for full-term infants.
2) Do not perform punctures on previous puncture sites as this poses a threat of infection.
3) Do not use the back of the heel or arch of the foot.
4) Always wipe away the first drop of blood.
