or
1.1 - 1.3 mmol/L (used often)

21

BUN
&
Creatinine

A

BUN: 10-20 mg/dL
Creatinine: 0.6-1.3 mg/dL

24
Q

LABS

Albumin

A

3.5-5.5 g/dL

25
Q

LABS

PT

A

11-14 sec

WEPT (warfarin, extrinsic, PT level)

26
Q

LABS

INR

A

1

Normal INR on Warfarin: 2-3

27
Q

LABS

PTT

A

21-34 sec

On heparin = varies (~60-100 secs) depending on your coag goals!

28
Q

LABS

ACT

Activating Clotting Time

A

80-120 secs

> 160-180sec for ECMO

> 400sec for CPB

Used for large heparin doses.

29
Q

LABS

FSP

Fibrin Split Products

A

<10 µ/dL

Fragments from dissolved clots. Used often for DIC

30
Q

LABS

Fibrinogen

A

160-450 mg/dL

(the netting that covers the clot)

31
Q

LABS

Plasminogen

A

62-130%

Plasminogen makes Plasmin. Plasmin degrades fibrin (or clots)

32
Q

LABS

FDP

Fibrin Degredation Products

A

<10 µ/mL

basically FSP but resulted in different units.

33
Q

LABS

D-Dimer

A

<250 ng/dL

Only detectable if you are currently breaking down lots of clots.

34
Q

LABS

TSH
T3
T4

A

TSH: 0.4 µ units/mL
T3: 90 -230 ng/dL
T4: 13 - 15 µ/dL

Control metabolism, temp, mood, weight, neuro fxn, & muscle strength.

T3 = MORE active, 7%, majority made in cells.
T4 = main circulating thyroid hormone, 93%, can be converted to T3 using iodinase.

35
Q

LABS

AST
ALT

A

<35 IU/L

Liver function - ALT more specfic to liver, AST involves other organs including the liver.
