RELATED APPLICATIONS [0001] This application claims the benefit under 35 U.S.C. .sctn. 119(e) of U.S. Provisional Application No. 60/652,660, filed Feb. 14, 2005, titled ANALYTE DETECTION SYSTEM; U.S. Provisional Application No. 60/724,199, filed Oct. 6, 2005, titled INTENSIVE CARE UNIT BLOOD ANALYSIS SYSTEM AND METHOD; U.S. Provisional Application No. 60/658,001, filed Mar. 2, 2005, titled SEPARATING BLOOD SAMPLE FOR ANALYTE DETECTION SYSTEM; and of U.S. Provisional Application No. 60/673,551, filed Apr. 21, 2005, titled APPARATUS AND METHODS FOR SEPARATING SAMPLE FOR ANALYTE DETECTION SYSTEM. The entire contents of each of the above-listed provisional applications are hereby incorporated by reference herein and made part of this specification. BACKGROUND [0002] 1. Field [0003] Certain embodiments disclosed herein relate to methods and apparatus for determining the concentration of an analyte in a sample, such as an analyte in a sample of bodily fluid, as well as methods and apparatus which can be used to support the making of such determinations. [0004] 2. Description of the Related Art [0005] It is a common practice to measure the levels of certain analytes, such as glucose, in a bodily fluid, such as blood. Often this is done in a hospital or clinical setting when there is a risk that the levels of certain analytes may move outside a desired range, which in turn can jeopardize the health of a patient. Certain currently known systems for analyte monitoring in a hospital or clinical setting suffer from various drawbacks. SUMMARY [0006] In some embodiments, a fluid handling module is configured for removable engagement with a reusable main fluid handling instrument. The module comprises a housing, an infusion fluid passageway, a sample fluid passageway, and a fluid component separator. The infusion fluid passageway has a first port and a second port spaced from the first port, and a lumen extending from the first port to the second port. The sample fluid passageway is connected to the infusion fluid passageway. The fluid component separator is connected to the sample fluid passageway. [0007] In some embodiments, a fluid handling module is configured for removable engagement with a reusable main fluid handling instrument. The module comprises a module housing and a first fluid passageway extending from the module housing. The first fluid passageway has a patient end remote from the housing. The first fluid passageway is configured to provide fluid communication with a bodily fluid in a patient. A fluid component separator is in fluid communication with the first fluid passageway. The fluid component separator is configured to separate at least one component from a portion of the bodily fluid drawn from the patient. [0008] In some embodiments, a method for extracting and preparing for analysis a bodily fluid of a patient is provided. The method comprises attaching a removeable fluid handling module to a main fluid handling instrument, wherein the fluid handling module comprises a module body, a fluid component separator connected to the module body, and a fluid passageway extending from the module body. The main fluid handling instrument comprises an analyte detection system. A volume of a bodily fluid is drawn from the patient into the fluid passageway. At least a portion of the drawn volume of bodily fluid is transferred to the fluid component separator. The fluid component separator separates a first component from the bodily fluid. The analyte detection system analyzes at least a portion of the separated first component to determine a concentration of an analyte. [0009] Certain objects and advantages of the invention(s) are described herein. Of course, it is to be understood that not necessarily all such objects or advantages may be achieved in accordance with any particular embodiment. Thus, for example, those skilled in the art will recognize that the invention(s) may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein. [0010] Certain embodiments are summarized above. However, despite the foregoing discussion of certain embodiments, only the appended claims (and not the present summary) are intended to define the invention(s). The summarized embodiments, and other embodiments, will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiments having reference to the attached figures, the invention(s) not being limited to any particular embodiment(s) disclosed.
